What is the volume of a hemisphere with a radius of 39.4ft, rounded to the nearest tenth of a cubic foot?

128099.5

Step-by-step explanation:

answers may vary to what the teacher wants as an answer but thats what i got according to delta math

V = 128099.454 m^3, or in terms of π V = 40775.3227 π m^3

Step-by-step explanation:

C = 15.7

A = 19.6

Step-by-step explanation:

The compass has a diameter of 5 centimetres.

Formula for a circumference of a circle: OR

We will use the second formula since we are given the diameter.

5 * 3.14 ≈ 15.7

The the circumference is about 15.7 inches.

Formula for area of a circle:

The radius of the compass is 2.5.

5 ÷ 2 = 2.5

19.6349540849 ≈ 19.6

The area is about 19.6 square inches.
