Shelby is in a hot air balloon where the balloon is shaped like a sphere with a diameter of 50 ft find the amount of space occupied by the balloon use 3.14 for pie and round your answer to the nearest tenth

50ft x 3.14 = 157ft

Step-by-step explanation:

It's asking for the circumference.

circumference formula:

To give you a better idea of the concept:

To make it simple, in a circle, there is the radius, diameter, and then the circumference.

Radius: The distance half way across the circle (see attachment below).

Diameter: The distance across the circle (see attachment below).

Circumference: The distance around the circle (see attachment below).

As you see, the radius is only half way across, so 2 times the radius would give us the full distance across (diameter).

(But this doesn't matter for this question because it already gave you the diameter (50ft), this was only so I could maybe help you understand the concept a bit more).

Your question:

Alright, it's asking for the circumference; all you have to do is the diameter (50 ft) times pi (3.14).

Hope this helped! :D

step-by-step explanation:

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
