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

Answer:they win 12 more matches in the second year
Step-by-step explanation:
Each year, the team plays a total of 120 matches. In its first year the team wins 45% of its matches. This means that the total number of matches that the team won in the first year is
45/100/× 120 = 54
The 2nd year ,the team wins 55% out of 120 matches. This means that the total number of matches that the team won in the second year is
55/100/× 120 = 66
Number of matches for the second year - number of matches for the first leg is 66 - 54 = 12
