Question

1. Given the image of the circle, identify the length of the radius, diameter, and circumference. Also, find the area. Make sure to show work (area and circumference) to receive credit. Choose a number for the diameter.

Answer 1

Radius = 5 units

Diameter = 10 units

Circumference = 10π units

Area = 25π square units.

Explanation:

i choose diameter.

Let's say the diameter of the circle is 10 units.

The radius of the circle can be found by dividing the diameter by 2:

Radius = Diameter / 2 = 10 / 2 = 5 units

The circumference of the circle can be found using the formula:

Circumference = 2πr = 2π * 5 = 10π units

The area of the circle can be found using the formula:

Area = πr^2 = π * 5^2 = 25π square units.

So, for a circle with a diameter of 10 units:

Radius = 5 units

Diameter = 10 units

Circumference = 10π units

Area = 25π square units.
