Answer:

MY BROTHER

Explanation:

He is very good in his studies and helps me in my studies too. He is very sincere and intelligent and never misses his school. I love my brother and always pray to God to help us maintain a strong bond forever.

Answer:

Explanation:

My brother is the most loveable person in my life. His name is Rahul and he is 21 years old, there is 1 years gap in between we two of us. Most siblings are always the most fighting peoples, and they never do anything together but my brother and I are not like that, we do everything together because we both love each other as he is my elder brother, he loves me a lot. We both live happily and throughout my life, he is my role model and I like to be more like him.

When I was 5 years, I would follow my brother around everywhere, I was the cute younger sister of my brother. This could be seen as a good or a bad thing. I was exposed to many things. In childhood, I was always hanging out with my brother and his friends, this also helped me to mature earlier. There is a phase in the younger years when we were in school my brother was very good in studies and I was not good in studies, that time he helped me in my studies very well. He was good enough to manage his studies and as well as mine.

Later, I become better in my studies and my parents felt very proud of my brother. He was self-dedicated and self-motivated towards his studies and career, today he is doing his masters. And always motivate me in the right direction, my brother is more than my parents to me because they are not worried about me as my brother takes care of me. I was always having an advantage of having an elder brother, I was getting the real-life experience by him and it helped me to get the best decision in my life.

Answer:

247 grams in kg = 247/1000= 0.247 kg. 44 kg 80 grams in kg = 44,080/1000= 44.08 kg.

Step-by-step explanation:

hope it helps

plz mark as brainliest

Answer:

247 gm =0.247 kg and 44kg.80 gm.=44.08 kg.

Step-by-step explanation:

1 gm.=1/1000 kg.

247 gm.=247×(1/1000)kg.

             =0.247 kg.

To convert 44 kg.80gm into kg. first of all we convert 80 gm into kg.

80 gm=80×(1/1000)kg.

           =0.08 kg.

Now both the term 44 kg. and 0.08 kg.is in same unit now we add both the terms

44 kg. 80 gm.=(44+0.08)kg.

                        =44.08 kg.

Answer:

(i) 50cm

(ii) 37 cm

Step-by-step explanation:

Part (i) : -

Given that

Radius of cone(r) = 14cm

Height of the cone(h) = 0.48m

                                    = (0.48 × 100)cm

                                h  = 48 cm

Slant height of the cone (l) ?

We know that

l² = h² + r²

l² = 48² + 14²

l² = 2304 + 196

l² = 2500

l = √2500

l = 50 cm

Thus slant height of the cone is 50 cm

Part (ii) : -

Given that

Base diameter of cone = 70cm

Radius of cone(r) = 70/2

                         r = 35 cm

and

Curved surface area of the cone = 4070 cm

πrl = 4070

π × 35 × l = 4070

(22/7) × 35 × l = 4070

22 × 5 × l = 4070

110 × l = 4070

l = 4070/110

l = 407/11

l = 37

l = 37 cm

Thus slant height of the cone is 37 cm    

Note:-

CSA of Cone =   πrl   

• Base radius is 14 cm of a cone
• Height is 0.48 m of that cone

• Slant height (l) of the cone ?

Using formula of calculating the slant height of cone (l),

• l² = h² + r²

Here,

• l is slant height
• h is height
• r is radius

But before putting the values in it we would be changing the unit of height (h) which is in metres into centimetres.

➺ h = 0.48 × 100

➺ h = (48/100) × 100

➺ h = 48 cm

Therefore, height of cone in centimetres is 48cm.

Putting all the required values,

➺ l² = (48)² + (14)²

➺ l² = (48 × 48) + (14 × 14)

➺ l² = (2304) + (196)

➺ l² = 2304 + 196

➺ l² = 2500

➺ l = √2500

➺ l = 50

Therefore, slant height (l) of the cone is 50 cm.

_____________________________________

• Curved surface area (C.S.A) of the cone is 4070 cm.
• Diameter is of 70 cm.

• Slant height (l) of the cone.

★ Curved surface area of cone :-

• C.S.A. = πrl

Here,

• Value of π is 22/7
• r is radius
• l is slant height

First of all we would be finding out the radius of the cone as we have been provided with its diameter.

As we know that,

➺ r = d / 2

By using it we gets,

➺ r = 70 / 2

➺ r = 35

Therefore, radius of the cone is of 35 cm.

Putting all the values in the formula,

➺ 4070 = (22/7) (35) (l)

➺ 4070 = 22/7 × 35 × l

➺ 4070 = 22 × 35 × l / 7

➺ 4070 = 22 × 5 × l

➺ l = 4070 / 22 × 5

➺ l = 814 / 22

➺ l = 407 / 11

➺ l = 37

Therefore, slant height (l) of the cone is of 37cm.

★ Volume of cone:-

• V = ⅓ πr²h

★ Total Surface Area of cone:-

• T.S.A. = πrl + πr²

Some more formulas related to concept surface area and volume :

★ Curved surface area of cylinder:-

• C.S.A. = 2πrh

★ Total surface area of cylinder:-

• T.S.A. = 2πr (h + r)

★ Volume of cylinder:-

• V = πr²h

★ Area of cross-section:-

• Area of cross-section = πr²

★ Volume of sphere:-

• V = 4/3 × πr³

★ Volume of cube:-

• V = a³

In these formulas,

• r is radius
• h is height
• a is side of cube
