Answer:
Hello,
Step-by-step explanation:
Area of the sphere:

Volume of the sphere:



Answer:
35 and 25.
Step-by-step explanation:
x+y=60
x-y=10
Subtract eq1 by eq2
x-x+y-(-y) = 60-10
2y=50
y=25.
x+25=60
x=35
Hope this helps :D

Answer:
shaded/square = (50π cm²)/(400 cm²) = π/8
Step-by-step explanation:
The quarter circle has area ...
A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²
The half-circle has area ...
A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²
Then the area of the shaded portion is ...
shaded = 100π cm² -50π cm² = 50π cm²
__
The area of the square is ...
A = s² = (20 cm)² = 400 cm²
Then the ratio of interest is ...
shaded/square = (50π cm²)/(400 cm²) = π/8
