How do you find the area of a circle if you know the diameter?

How to find the area of a circle: The area of a circle can be found by multiplying pi ( π = 3.14) by the square of the radius. If a circle has a radius of 4, its area is 3.14*4*4=50.24. If you know the diameter, the radius is 1/2 as large.

What is the formula for finding the area of a circle?

The formula for the area of a circle is pi multiplied by the radius of the circle squared. The radius of the circle is the length of a straight line stretching from the center of the circle to the line of circumference. It is equal to half the diameter.

What is the unit of area of a circle?

The area of a circle is the number of square units inside that circle. If each square in the circle to the left has an area of 1 cm2, you could count the total number of squares to get the area of this circle.

What is the formula for finding the diameter of a circle?

The diameter of a circle can be calculated using the formula d = 2r, where "d" indicates the diameter and "r" denotes the radius of the circle. In terms of circumference, the diameter can be computed using the equation d = c/pi, where "c" represents the circumference and pi is approximately equivalent to 3.142.
