The diameter of a golf ball is 1.68 inches. What is the volume of the golf ball? 19.86 cubic inches
2.48 cubic inches
2.99 cubic inches
18.35 cubic inches

B

Step-by-step explanation:

V = (4/3) * pi * r^3

d = 1.68 inches

r = d/2

r = 1.68/2 = .84 inches.

V = (4/3) * 3.14 * 0.84*0.84 * 0.84

V = 1.33333 * 3.14 * 0.5927

V = 2.48 cubic inches.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
