Answer:

$5 \times 108 - 3.4 \times 108$

lets take 108 as X

$5x - 3.4x = 2x \\ \\ 1.6x = 108 \times 1.6\\ = 172.8$

The total surface area of a hemisphere is 45 <img src="https://tex.z-dn.net/?f=%5Cpi%5Cp" id="TexFormula1" title="\pi\p" alt=

rjkz [21]

Answer:

The volume of the hemisphere

V = 121.33086 cubic centimeter

Step-by-step explanation:

Step(i):-

Given that the total surface area of a hemisphere = 45π cm²

The total surface area of a hemisphere = 3π r²

Equating

3π r² = 45π

$r^{2} = \frac{45}{3} =15$

r = $\sqrt{15} = 3.87$

The radius of the sphere 'r' = 3.87

Step(ii):-

The volume of the hemisphere

$V = \frac{2}{3} \pi r^{3}$

$V = \frac{2}{3} \pi (3.87)^{3}$

we know that π = 3.14

$V = \frac{2}{3} (3.14) (3.87)^{3}$

V = 121.33086 cubic centimeter
