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

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

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
