Answer 2

Question:-

Find the surface area of a sphere of radius 1m.

Given:-

• Radius of Sphere = 1m

To Find:-

• Surface Area of a Sphere

Formula Used :-

• Surface area of a sphere: 4πr²

Answer: 12.57 m²

ㅤ

Solution:-

Surface area of a sphere of radius (R) = 4πr²

Value of π can be written as

ㅤㅤπ = $\frac{22}{7}$

ㅤㅤ= $4\times\frac{22}{7} \times 1$

ㅤㅤ= $\frac{88}{7}$

ㅤㅤㅤ= 12.57 m²

Additional info:-

The surface area of a sphere: The region covered by its outer surface in three - dimensional space.

• It is a three dimensional circle.

• The surface area of the sphere is equal to the area of four circles.

• Thus, Surface area of a sphere is 4πr²

Hope it helps ya!!
