What is the radius of a hemisphere with a volume of 8231 cm3

radiusr = 15.7808841 cm

Step-by-step explanation:

base circumferenceC = 99.1542189 cm

volumeV = 8231 cm³

curved surface areaA = 1564.74123 cm

base surface areaB = 782.370617 cm²

total surface areaK = 2347.11185 cm²

In Terms of Pi π

base circumferenceC = 31.5617681 π cm

volumeV = 2620.00867 π cm³

curved surface areaA = 498.072604 π cm²

base surface areaB = 249.036302 π cm²

total surface areaK = 747.108906 π cm²

Hemisphere Formulas in terms of radius r:

Volume of a hemisphere:

V = (2/3)πr³

Circumference of the base of a hemisphere:

C = 2πr

Curved surface area of a hemisphere (1 side, external only):

A = 2πr²

Calculate the base surface area of a hemisphere (a circle):

B = πr²

Total surface area of a hemisphere:

K = (2πr²) + (πr²) = 3πr²
