The surface area of a sphere
324 square centimeters. what is volume in cubic centimeters, of the sphere? express your answer in terms of pi

The surface area of the sphere is SA = 324π cm².

Calculate the surface area of the sphere by using the formula: SA = 4πr².

To find the value of r, substitute SA = 324π in the above formula.

324π = 4πr²

81 = r²

r = ± 9.

The measurements of the sphere cannot be expressed in negative sign.

The radius of the sphere is r = 9 cm.

Calculate the surface area of the sphere by using the formula: V = (4/3)πr³.

Substitute r = 9 in the above formula

V = (4/3)π 9³ = 972π cm³.

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
