Answer:

Radius=10

Diameter=20

circumference=62.8

Area=314

Answer:

Radius: 10 inches

Diameter: 20 inches

Circumference: 62.8 inches

Area: 314 inches squared

Step-by-step 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
