Question

Find the volume of the following shapes: (i) Pyramid (ii) Cone 8 in loft Gin loft V= V=

Answer 1

Area and Volume of a Sphere.

The correct answer are; Area = 2,828.6 square centimeters ;

Volume of the Sphere = 14,142.9 cubic centimeters.

$\begin{gathered} \text{Area of a Sphere = 4}\pi r^2 \\ \text{Where r =15cm} \\ \text{Area of Sphere =4}\times\frac{22}{7}\times15^2=\text{ 2828.571 }\approx2828.6cm^2 \end{gathered}$$\text{Volume of Sphere =}\frac{4\pi r^3}{3}\text{ = }\frac{4\times\frac{22}{7}\times15^3}{3\times7}\text{ =}\frac{4\times22\times15^3}{21}=14142.857\text{ }\approx14142.9cm^3$

Hence, the correct answer are;

Area = 2,828.6 square centimeters, and

Volume = 14,142.9 cubic centimeters.
