Step-by-step explanation:
3.
The formula of a volume of a sphere:
R - radius
We have R = 3.15 m. Substitute:
4.
The formula of a volume of a cone:
r - radius
H - height
We have 2r = 11.6 → r = 5.8 and H = x. Substitute:
6.
The formula of a volume of a cube:
s - edge
We have s = 1.02 in. Substitute:
Answer:
multiply the radius by 2π
Step-by-step explanation:
The formulas for circumference of a circle is
C = πD where D is the diameter,
or
C = 2πr where r is the radius.
Either formula is correct, but we will work with the second one since the question is asking about radius.
We see that 2π(r) = the circumference, so multiply r by 2π to get the circumference
