Question

Find the circumference and area of a circle to the nearest hundredth. Use 3.14 for pie. Round to the nearest hundredth if necessary. The diameter is 52.

Answer 1

• Circumference = 163.28 units

• Area = 2,122.64 units²

Explanation:

Circumference

Circumference of a circle is calculated by the formula:

= π * diameter

= 3.14 * 52

= 163.28 units

Area

Area of a circle is calculated by the formula:

= π * radius²

Radius = DIameter / 2

= 52 / 2

= 26 units

Area = 3.14 * 26 * 26

= 2,122.64‬ units²
