# How many square inches are in a 12 inch circle?

## How many square inches are in a 12 inch circle?

To find the area of a circle, you need to use the formula A=π⋅r2 , therefore the area A is π⋅62≈113 square inches. To find the circumference of a circle, you will use the formula C=2⋅π⋅r , therefore the circumference C is 2⋅π⋅6≈38 inches.

## What is the radius of a 10 inch circle?

The relation of radius to diameter is , or . So 3.1415926 * 10 = 31.142″ if we round to thousandths of an inch. If the diameter is 8 inches, the radius is 4 inches.

## How do you find the square inches of a circle?

Measure the radius of the circle. Multiply the radius by the radius. For example, if you have a 18 inch radius, you would multiply 18 inches by 18 inches to get 324 square inches. Multiply the step 2 result by 3.1415, an approximation of pi, to find the circular area.

## How many square inches is an 8 inch circle?

## What is the diameter of a 10 circumference circle?

31.42cmSince the diameter is 10cm, we know that C = π x 10cm = 31.42cm (to 2 decimal places).

## What are the measurements of a circle?

DefinitionsRadius is the length from the midpoint of the circle to the outer edge of the circle. Diameter is the full length of the circle running from the edge, through the midpoint, all the way to the other side. Now, circumference is the distance around the outside edge of this circle.

## How do you find the square foot of a circle?

The formula for determining the total square feet in a circular area is: A = Pi x R2 (Area = Pi x R-squared). This formula may mean nothing to you so here's a explanation: To determine the total square footage in a circular area you will first need to determine the radius (R) of the circle.

## How do you measure a round circle?

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.
