Question

The area of a circular table is 22511 in2.

Answer 1

Answer:

1. Radius = 84.65 in

2. Circumference = 531.65 in

3. Diameter = 169.3 in

Step-by-step explanation:

1] In order to find the area of a circle, we use the formula

Area of a circle = πr²

Where r is the radius. So substitute the value of the area of the circle in the formula, to find the radius r.

22511 = π r²

r² = 22511 ÷ π

r = $\sqrt{22511 / \pi }$

r = 84.65 in

2] Now that we found the radius, we can easily find the circumference using the formula:

Circumference of a circle = 2πr

Substitute the value of r in the formula.

Circumference = 2 × π × 84.65

Circumference = 531.87 in

3] The diameter is twice the radius, so:

diameter = r × 2

diameter = 84.65 × 2

diameter = 169.3 in
