Answer:
12.4 cm
Step-by-step explanation:
Use the sphere volume formula, V = r³
Plug in the volume and solve for r, the radius:
V = r³
7961 = r³
1900.55 = r³
12.39 = r
So, the radius of the sphere is approximately 12.4 cm
Answer:
% area of the shaded region = 33%
Step-by-step explanation:
Radius of the middle circle = 7 cm
Radius of the inner circle = 4 cm
Area of the middle circle = πr²
= π(7)²
= 49π
Area of the inner circle = π(4)²
= 16π
Area of the shaded region= 49π - 16π
= 33π
Area of the outermost circle = π(10)²
= 100π
% area of the shaded region =
=
= 33%
Therefore, area of the shaded region is 33% of the complete logo.
