Answer:
a] Radius of circle = 10 feet
Circumference of circle = 94.2 feet (Approx.)
Area of circle = 314 feet² (Approx.)
b] Radius of circle = 6 cm
Circumference of circle = 37.68 cm (Approx.)
Area of circle = 113.04 cm² (Approx.)
Step-by-step explanation:
Given:
a] Radius of circle = 10 feet
b] Radius of circle = 6 cm
Find:
Circumference an area for both circle
Computation:
Circumference of circle = 2πr
Area of circle = πr²
a] Radius of circle = 10 feet
Circumference of circle = 2(3.14)(10)
Circumference of circle = 94.2 feet (Approx.)
Area of circle = (3.14)(10)²
Area of circle = 314 feet² (Approx.)
b] Radius of circle = 6 cm
Circumference of circle = 2(3.14)(6)
Circumference of circle = 37.68 cm (Approx.)
Area of circle = (3.14)(6)²
Area of circle = 113.04 cm² (Approx.)
