Question

A sphere of diameter 10 inches is cut by a plane which passes through its center. Find the area of the cross-section, leaving the answer in terms of π. A) 10π in2 B) 25π in2 C) 50π in2 D) 96π in2

Answer 1

When a sphere is cut by a plane which passes through the center, it will create a circle that has the same diameter of the sphere.

To represent this area, you will use the formula for finding area of a circle.

A= pi x r^2
Pi x 5^2
A = 25 x pi or choice B
