Answer:
radius r = 15.7808841 cm
Explanation:
base circumference C = 99.1542189 cm
volume V = 8231 cm³
curved surface area A = 1564.74123 cm
base surface area B = 782.370617 cm²
total surface area K = 2347.11185 cm²
In Terms of Pi π
base circumference C = 31.5617681 π cm
volume V = 2620.00867 π cm³
curved surface area A = 498.072604 π cm²
base surface area B = 249.036302 π cm²
total surface area K = 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
