Find the surface area of a ping pong ball if the diameter of a ping pong ball is 1.4882 inches round your answer to the nearest hundredth

6.96 in².

Step-by-step explanation:

The formula for the surface area of a sphere is

A= 4πr²

Data:

d = 1.4882 in

Calculations:

r = d/2 = 1.4882/2 = 0.7441 in

V = 4 × π × 0.7441² = 6.96 in²

The surface area of the ping pong ball is 6.96 in².

question:

could we have options?

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
