Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi
radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi
Radius x 2 x 3.14 = Area * * * * * That is the formula for the circumference! The area = pi*radius2
The circumference is 4pi
pi*radius2 = area radius = square root of (area/pi) circumference = 2*pi*radius
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
you use pi to calculate the area or circumference of a circle
By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
To calculate the circumference of a circle from its area, first use the formula for the area ( A = \pi r^2 ). Given that the area is 8.2 cm², you can solve for the radius ( r ) by rearranging the formula: ( r = \sqrt{\frac{A}{\pi}} ). Once you find the radius, use the circumference formula ( C = 2\pi r ) to calculate the circumference.
you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi
pi times diameter = circumference
To find the circumference of a circle given its area, we can use the formulas for area (A = \pi r^2) and circumference (C = 2\pi r). First, we solve for the radius (r) using the area: (r = \sqrt{\frac{A}{\pi}} = \sqrt{\frac{5.3}{\pi}} \approx 1.303). Then, we calculate the circumference: (C = 2\pi r \approx 2\pi \times 1.303 \approx 8.179). Thus, the circumference is approximately 8.18.
Circumference C = 2 r times pi C = 119.38052083641213 centimeters. Area A = r2 times pi. A = 1134.0815 square centimeters.
To calculate the circumference and area of a circle, you need the radius (r) or diameter (d). The circumference (C) is given by the formula ( C = 2\pi r ) or ( C = \pi d ). The area (A) is calculated using the formula ( A = \pi r^2 ). If you provide the radius or diameter in centimeters, I can give you the specific values for circumference and area.
The area of a circle (A) is pi x r x r.The circumference of a circle (C) is pi x d, or pi x 2r.So if you know C, you can calculate r using the formula C = pi x 2r or r = C/2piOnce you know r, you can calculate A using the formula A = pi x r x r
