A ball has a radius of 1 foot. What is the surface area of the ball?
Solution:
The total area occupied by the surfaces of an object is called its surface area.
The surface area is classified into two categories:
Curved surface area or Lateral surface area
Total surface area
Given, radius of ball = 1 foot
We have to find the surface area of the ball.
The surface area of the ball is given by
A = 4πr2
Where r is the radius
So, A = 4π(1)2
A = 4π
Use π = 3.14
A = 4(3.14)
A = 12.56 square feet.
Therefore, the surface area of the ball is 12.56 square feet.
A ball has a radius of 1 foot. What is the surface area of the ball?
Summary:
A ball has a radius of 1 foot. The surface area of the ball is 12.56 square feet.
