What is the perimeter and area of a circle with diameter equal to 5cm?
cicumference = pi*5 cm area = pi*2.52 square cm
How do you find the area and perimeter of circle?
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
How do you find area and perimeter of a circle?
The area of a circle is described by the equations: A=πr2 and the perimeter of a circle is described by the equation: C=πd where: A is the Area C is the circumference, or perimeter r is the radius d=diameter=2r π= pi, the ratio of diameter to circumference (3.14159)
What is the diameter and area of a circle?
the diameter of a circle is defined by the largest length from one side of the circle to the other side of the circle. the area of a circle is equal to pi(3.14) times the radius squared. the radius is equal to half of the diameter.
What is the diameter of a circle with an area equal to 113.04 square units?
The diameter of the circle is 11.997 units.

When does the area of a circle equal 8.21?
When the diameter is about 1.62.
How do you find the area of a circle when you are only given its perimeter?
The Perimeter of a circle is it's circumference. And the circumference is the diameter times pi. So to find the area, divide the circumference by pi, and get the diameter. Then divide the diameter by 2, to get the radius. Then multiply the radius times itself, and multiply that by pi.
What is the area of a circle with diameter equal to 15 ft?
The circle's area is 176.71 square feet.
What would the diameter of two circles of equal size be relative to the diameter of one circle of equal area?
it would be the diameter of the smaller circle times sqrt 2
What is the diameter of a circle with an area equal to 113.04sqm?
12 meters.
How does area of a circle relate to circumference?
The area of a circle is equal to the perimeter times half the radius. That is, A = P*r/2
What is the area of a circle if it has a diameter which is 18 feet long?
The area of a circle is equal to πr2 where π (pi) is equal to approximately 3.142 and r represents the radius of the circle. Because the question gives you the diameter and not the radius you have to use the measurement of the diameter to calculate the radius. Remember that the radius is equal to half the diameter. So if the diameter is equal to 18 feet, then the radius of this particular circle is equal to 9 feet. Plugging this into our equation for area we get: area = π(92) area = 3.142(81) area = about 254.5 ft2 (don't forget that the answer is in squared feet not just feet)
