How do you find circumference with area?

The formula C = 2√πA is designed to find a circle’s circumference using the area (A). Alternatively, you can solve the equation A = πR2 in reverse to find R, then plug R into the circumference equation. Both equations provide the same result.

What is the diameter of the circle?

2 x radius

What is circumference vs diameter?

The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.

What is the similarity between circumference and diameter?

Circles are all similar, and “the circumference divided by the diameter” produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

Is diameter half the circumference?

The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c). Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).

How do you calculate the diameter of a circle?

How do you find the circumference of a circle with the diameter?

What is the diameter of a 90 inch circle?

Here is the answer to questions like: how to find the area of a circle with diameter 90 inches?…What is the area of a circle with diameter 90 inches?

Result: The area of a circle with diameter 90 is 6362
Formulae:
r = 45 d = 90 C = 283	A = πr2 = π(d2)2 A = C24π π = 3.1415 A = area C = circumference or perimeter r = radius, d = diameter

How do you convert diameter to radius?

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.

What is Radius and Diameter?

The diameter is a straight line that passes through the center of the circle. The radius is half of the diameter. It starts from a point on the circle, and ends at the center of the circle.

What is the radius of a 30cm circle?

What is the area of a circle with radius 30 cm?

Result: The area of a circle with radius 30 is 2827
Formulae:
r = 30 d = 60 C = 189	A = πr2 = π(d2)2 A = C24π π = 3.1415 A = area C = circumference or perimeter r = radius, d = diameter

What is the circumference with a radius of 4?

Answer: 8 π The circumference of a circle is its boundary or the length of the complete one of a circle.

What is the radius if the diameter is 16?
