The largest cross-section of the sphere shown has an approximate area of 28.27 cm2, what is the approximate volume of the sphere
? A) 14.14 cm3 B) 113.1 cm3 C) 226.2 cm3 D) 904.78 cm3
2 answers:
Answer:
B) 113.1 cm³
Step-by-step explanation:
The cross-section of a sphere is a circle. The area of a circle is:
A = πr²
The largest cross section passes through the center of the sphere, where the radius of the circle equals the radius of the sphere.
28.27 = πr²
r = 3.00
The volume of the sphere is therefore:
V = 4/3 π r³
V = 4/3 π (3.00)³
V = 113.1
