Answer:
please see detailed answers below
Explanation:
1) circumference = πd = 16π inches.
arc length = (15/360) X πd = (2/3)π inches.
area of circle = πr² = π(8)² = 64π square inches.
area of sector = (15/360) X 64π = (8/3)π square inches.
2) circumference = πd = 30π inches.
minor arc length = (60/360) X 30π = 5π inches.
major arc length = (300/360) X 30π = 25π inches.
area of circle = πr² = π(15)² = 225π square inches.
area of minor sector = (60/360) X πr² = (75/2)π square inches.
area of major sector = (300/360) X πr² = (375/2)π square inches.
3) circumference = πd = 40π inches.
arc length = (125/360) X 40π = (125/9)π inches.
area of circle = πr² = π(20)² = 400π square inches.
area of sector = (125/360) X 400π = (1250/9)π square inches.
