Answer:
Radius: 10 inches
Diameter: 20 inches
Circumference: 62.8 inches
Area: 314 inches squared
Explanation:
Radius:
They have already given you the radius (10), so no formula is needed.
Diameter:
To find the diameter, multiply the radius by 2, so:
2 × 10 = 20
Circumference:
To find the circumference, use this formula:
C=2πr
2 × π (3.14) = 6.28
6.28 * 10 = 62.8
Area:
To find the area, use this formula:
A=πr²
π (3.14) × 100 = 314

Have a good day :)
