The surface area of a ball is 576 pi square millimeters. What is the ball’s radius? Recall the formula S A = 4 pi r squared. 12
Nuetrik [128]

Answer:

r = 12 millimeters

Step-by-step explanation:

Surface area of a ball = 4πr²

Surface area of a ball = 576 pi square millimeters

Surface area of a ball = 4πr²

576π = 4πr²

r² = 576π / 4π

r² = 144

Find the square root of both sides

√r² = √144

r = 12

r = 12 millimeters

Identify the value of x that makes each pair of ratios equivalent. X to 50 and 16 to 25
olasank [31]

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ x = 32

x:50

16:25

The pattern here is divide by 2 (or if doing the opposite way, multiply by 2.)

16 x 2 = 32, so x = 32
