What is the radius and area of a circle if the circumference is 157?
The radius and area of a circle if the circumference is 157 are:r = 25A = 1,960
What is the circumference of a circle with 7cm the radius?
The circumference of a circle with a 7cm radius is 44cm. The area is 154cm2
How do i find circumference and area of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
What is the area and the circumference of a circle?
area: pi times radius squared circumference: pi times radius
What is the area and circumference of a circle with the radius of 9.5 mm?
The area and circumference of a circle with a radius of 9.5 mm are:A = 284mm2C = 59.7mm
What is the area of the circumference of a circle with diameter 7 yd?
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
How is pi in relation to a circle?
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
What is the circumference and area of a circle if the radius is 9.6 millimeters?
A circle with a radius of 9.6 millimeters has a circumference of 60.32 millimeters.
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find out the radious of a circle?
The radius of a circle is the distance from the centre of the circle to a point on the circumference of the circle. If it is a drawing and the circle is to scale the radius can be measured with a ruler. If not, the radius can be calculated if the diameter, circumference or area of the circle is known. the radius is equal to: - the diameter divided by 2 - the circumference divided by 2pi(approx. 6.284) - the square root of the area divided pi (divide by pi first, then take the square root)
What is the circumference and the area of a circle with a radius of 3?
28.26=area 18.84=circumference
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
