If the sphere has a volume of approximately 904.78 cm3, what is the approximate area of the largest cross-section of the sphere shown? A) 28.27 cm2 B) 113.1 cm2 C) 226.2 cm2 D) 452.39 cm

D

Area = 452.39cm^2

Step-by-step explanation:

Given that a sphere has a volume of approximately 904.78 cm3

Volume of a sphere V = 4/3πr^3

904.78 = 4/3/πr^3

r^3 = 216

r = 6 cm

The approximate area of the largest cross-section of the sphere will be

A = 4πr^2

A = 4π6^2

A = 452 .39cm^2

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
