what is the name of fandom name of mamamoo?​

Answer:

a)10.39

b)343

c)308

d)l=25

e)TSA 1870

Step-by-step explanation:

a)

length of diagonal is equal to

[tex] \sqrt{3} \: x [/tex]

x is side

so √3X6

10.39

b)

volume of cube is equal to

[tex] {s}^{3} [/tex]

=7X7X7

343

c)

CSA of hemisphere is

[tex]2\pi {r}^{2} [/tex]

=2X(22/7)X7X7

308

d)

slant hight

so r = 7 h=24 l= ?

using Pythagoras theorem

[tex] {l}^{2} = {h}^{2} + {r}^{2} [/tex]

l2=24X24+7X7

l=√625

l=25

e)

TSA of hemisphere+ TSA of cone =TSA of icecream

TSA of cone =

[tex]3\pi {r}^{2} [/tex]

so 3X22/7×7×7

=462

TSA of cone is

[tex]\pi {r}^{2} + \pi \: rl \: + \pi \: r \ (l + r)[/tex]

154+550+704

=1408

adding both we get

icecream TSA =1870

Answer: 750m

Step-by-step explanation:

From the figure, it can be observed that the Height of 1st step is ¼ m

Height of the 2nd step is (¼ + ¼) m = ½ m

Height of 3rd step is (¼ + ¼ + ¼) m = 3/4 m

Therefore, the height of each step is increasing by ¼ m

Length 50m and width (tread) is the same for each step that is ½ m

Volume of step can be considered as Volume of Cuboid = length × breadth × height

Volume of concrete in 1st step = 50m × ½ m × ¼ m = 6.25 m³

Volume of concrete in 2nd step = 50m × ½ m × ½ m = 12.50 m3

Volume of concrete in 3rd step = 50m × ½ m × ¾ m = 18.75 m3

It can be observed that the volumes of concrete in these steps are in an A.P.: 6.25m³, 12.50m³, 18.75m³, ....

First term a = 6.25, Common difference d = 6.25

Let nth term of AP  be the 15th value since number of steps = 15

Sum of n terms, Sₙ = n/2 [2a + (n - 1) d]

S₁₅ = 15 / 2 [2 × 6.25 + (15 - 1) × 6.25]

= 15 / 2 [12.50 + 14 × 6.25]

= 15 / 2 [12.50 + 87.50]

= 15/2 × 100

= 750 m³

Therefore, the volume of concrete required to build the terrace is 750 m³.

[tex]\large\underline{\sf{Solution-}}[/tex]

Given that,

A small terrace at a football ground comprises of 15 steps each of which is 50 m long and built of solid concrete. Each step has a rise of ¼ m and a tread of ½ m.

It means,

Length of each step, l = 50 m

Breadth of each step, b = \dfrac{1}{2} m

Let assume that h represents the height of first step and h = \dfrac{1}{4} m

Now,

[tex] \red{\sf \:Volume\:of\:concrete\:used\:in\:first\:step, \: V_1 = lbh \: {m}^{3} }\\ \\ [/tex]

[tex] \red{\sf \:Volume\:of\:concrete\:used\:in\: {2}^{nd} \:step, \: V_2 = lb(2h) = 2lbh \: {m}^{3} }\\ \\ [/tex]

[tex] \red{\sf \:Volume\:of\:concrete\:used\:in\: {3}^{rd} \:step, \: V_3 = lb(3h) = 3lbh \: {m}^{3} }\\ \\ [/tex]

[tex] \red{\sf \:Volume\:of\:concrete\:used\:in\: {15}^{th} \:step, \: V_{15} = lb(15h) = 15lbh \: {m}^{3} }\\ \\ [/tex]

So, Total volume of concrete required to built the terrace is

[tex] \sf \: = \: V_1 + V_2 + V_3 + \cdots \cdots \: + \: V_{15} \\ \\ [/tex]

[tex] \sf \: = \: lbh + 2lbh + 3lbh + \cdots \cdots \: + \: 15lbh \\ \\ [/tex]

[tex] \sf \: = \: lbh \: (1 + 2 + 3 + \cdots \cdots \: + \: 15) \\ \\ [/tex]

We know,

[tex]\boxed{ \bf{ \:1 + 2 + 3 + \cdots \cdots + n = \frac{n(n + 1)}{2} \: }} \\ \\ [/tex]

So, using this result and also on substituting the values of l, b and h, we get

[tex] \sf \: = \: 50 \times \dfrac{1}{2} \times \dfrac{1}{4} \times \bigg(\dfrac{15(15 + 1)}{2} \bigg) \\ \\ [/tex]

[tex] \sf \: = \: 25 \times \dfrac{1}{4} \times \bigg(\dfrac{15 \times 16}{2} \bigg) \\ \\ [/tex]

[tex] \sf \: = \: 25 \times 15 \times 2 \\ \\ [/tex]

[tex] \sf \: = \: 750 \: {cm}^{3} \\ \\ [/tex]

[tex]\bf\implies \:Volume\:of\:concrete\: = 750 \: {m}^{3} \\ \\ [/tex]
