Question

The volume to a cylinder is 200 cm^3 it's height is 10 cm then find the area of its base

Answer 1

Volume of Cylinder=200cm³
Height of Cylinder=10cm

We know that cylinder Volume
=πr²h
A/Q
$\pi {r}^{2} h = 200 \\ = \frac{22}{7} \times {r}^{2} \times 10 = 200 \\ = {r }^{2} = \frac{200 \times 7}{22 \times 10} \\ {r}^{2} = \frac{70}{11}$
Radius²=70/11 cm

Base of Cylinder is Circle
Area of Circle=πr²
R²=70/11
$area = \frac{22}{7} \times \frac{70}{11} \\ = 20 {cm}^{2}$
Area of base=20cm²

(π=22/7),(r²=70/11)
