Answer:
120π
Step-by-step explanation:
diameter = 120
radius = 60
Cirumference= 2πr
2 x π x 60 = 120π
The answer for this would be 1.5
if the sphere has a diameter of 5, then its radius is half that, or 2.5.

Answer:
A. -2 + 12 -2 ^ 3 + 2 ^ 0 * 3
= 10 - 2 ^ 3 + 2 ^ 0 * 3
= 10 - 8 + 1
= 3
B. 9 ^ (1/2)(25) - 8 + 2 + 3 ^ 2
= 9 ^ (1/2)(25) - 6 + 9
= 3 ^ 25 + 3
= 3 ^ 25 + 3
= 847288609446
C. 1/2 * 3/5 * (2 ^ 3 - 6) + 1/5
= 1/2 * 3/5 * 2 + 1/5
= 3/5 + 1/5
= 4/5
That’s 125 times 9!!! which is 1125!!!
