Answer:
r=9
Step-by-step explanation:
45/360=1/8
1/8*2=2/8
2/8=1/4
1/4*pi*r=(9pi)/4
Divide both sides by 1/4 (the fours cancel each other out)
Pi*r=9*pi
Pi cancels each other out
R=9

Answer:
1774.67π mm³
Step-by-step explanation:
Please find attached to this question, the required diagram.
From the question, we are told we have a spherical mold.
We would find the volume of a spherical mold using the formula for the volume of a sphere.
The volume of a sphere is calculated as : 4/3πr³
From the attached diagram, we are given the Diameter do the spherical mold as: 22mm
Radius of the spherical mold = Diameter ÷ 2 = 22mm÷ 2 = 11mm
The volume of the spherical mold = 4/3 × π × 11³
= 1774.6666667π mm³
Approximately and leaving it in terms of pi (π)= 1774.67π mm³
