DO NOT POST UNUSEFUL ANSWERS! Serious answers only! A softball has a circumference of 12 inches. What is the softballs approximate volume? A. 16.41 in^3 B. 24.56 in^3 C. 29.18 in^3 or D. 31.27 in^3

Formula for volume of a sphere: V = (4 / 3)(pi)(r^3)

Formula for circumference: C = (pi)(2r)

Solving for radius using circumference formula:

12 = (pi)(2r)

2r = 12 / pi

r = 12 / 2pi

Solving for volume:

V = (4 / 3)(pi)((12 / (2pi))^3)

Plug into calculator

V = 29.18 in^3

Hope this helps!! :)

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
