Ответ:
The surface area of a sphere that is 8 inches is 201.06in²
Ответ:
64 π inches^2 or 201.06 inches^2 to the nearest hundredth.
Step-by-step explanation:
The radius = 1/2 * the diameter
= 1/2 * 8
= 4 inches.
The surface area = 4 π r^2
4 π 4^2
= 64 π inches^2
or 201.06 inches^2 to the nearest hundredth.
Ответ:
That simplified is 1/4.
So multiply 18 by 1/4.
18 × 1/4
= 18/4
= 9/2
= 4.5
This is your answer.
