why is the volume of this hemisphere 2,786 cm^3
use n=3.14 to round answer to the nearest whole
explain how I found the volume
V = 1/2 x 4/3 nr^3
diameter=22cm
To find the volume of a hemisphere, you can use the formula V = 1/2 x (4/3) x π x r^3. Given that the diameter of the hemisphere is 22 cm, the radius (r) of the hemisphere is half of the diameter, which is 11 cm.
Plugging in the value of the radius into the formula, we get:
V = 1/2 x (4/3) x π x 11^3
V = 1/2 x (4/3) x 3.14 x 1331
V = 2/3 x 3.14 x 1331
V = 2,786.32 cm^3
Rounded to the nearest whole number, the volume of the hemisphere is 2,786 cm^3.
