Spheres

Question 3 • Reading HS- Integrated Math I

A company produces individually wrapped spherical biscuits. The minimum amount of wrapping material needed to cover a biscuit, assuming no edges overlap, is 200.96 square centimeters. What is the diameter of one biscuit? (Use 3.14 for the value of π.)

Answer
A
4 cm
B
8 cm
C
16 cm
D
64 cm

Explanation

The surface area of a sphere is 4πr². Using π = 3.14, 200.96 = 12.56r², so r² = 16 and the radius is 4 cm. The diameter is twice the radius, or 8 cm, which is choice B.
