Find the surface area of a sphere with radius 10 in. Leave your answer in terms of pi.
Solution:
The area covered by the outer surface of the sphere is known as the surface area of a sphere.
A sphere is a three-dimensional solid object which has a round structure, like a circle.
The difference between a sphere and a circle is that a circle is 2-dimensional, whereas a sphere is a 3-dimensional shape.
It is given that
Radius of the sphere = 10 inches
The formula to find the surface area of a sphere is
A = 4πr2
Where r is the radius
Substituting the values
A = 4π(10)2
A = 4π(100)
A = 400π square inches
Therefore, the surface area of a sphere is 400π square inches.
Find the surface area of a sphere with radius 10 in. Leave your answer in terms of pi.
Summary:
The surface area of a sphere with radius 10 in is 400π square inches.
