What is the formula for the area of the circle given the diameter?
in place of r (radius) write d/2 where d is diameter
How do you find diameter of a circle with the diameter 10?
You have answered this question for yourself; the answer is '10' Do you mean to ask ; What is the circumference/area of a circle, with a diameter of '10'?. If so , commit to memory ' elementary school maths. A = pi r^2 C = 2 pi r or pi d . From this 2r = d Hence 2r = 10 r = 5 C = 10 pi = 31.41592.... units A = pi 5^2 = 25 pi = 78.5398... units^2
What is the formula used to calculate probability?
force over area=pressure
What is the area of a circle with a diameter of 8?
Commit to memory A = pi r^2 C = 2 pi r or pi d NB 2r = d This is elementary school maths. Hence if d = 2r 8 , then r = 8/2 = 4 Hence A = pi 4^2 A = 16 pi pi is a constant at 3.141592.... A = 16*3.41592.... = 50.26554.... units^2
Find the area of a box?
The question is ambiguous. I can determine the outside area of a closed box, given its height H, width W and depth D. The top and bottom are equal area, D x W. The front and back are equal area, H x W. The right and left sides are equal, H x D. So, we have 2 x (DW+HW+HD) = total outside area. If all sides are equal, we have 6xL^2, where L is the length of one of the sides.
How do you calculate the diameter of a 3 acre circle?
Divide the area by Pi to get the diameter.
What is the format to calculate the area of a diameter?
pi is a constant = 3.141592654 . . . . circle area = pi * ( ( diameter/2 )2 )
How do you calculate the area of a cone's base?
The base of a cone is a circle. The area of a circle is found by multiplying the diameter by Pi.
What is the mathematical formula for finding the radius of a circle?
To calculate this you will need the diameter of the circle. The formula is: diameter/2*pi If you don't know the diameter you can also use the area of the circle: Sqrt(Area/pi) = radius
How do you calculate the diameter or radius of each circle?
Using the Circumference And Area.
What is the equation to calculate the area of a circle if you know the diameter?
Area= Pi r squared
How to calculate area of circle within a circle?
Take out the diameter of the outer circle from the distance between the two. Gives you the diameter of the inner circle then pi r squared it.
What may be calculated from its diameter?
If by "it" you mean a circle, once you know the diameter, you can calculate its radius, its circumference, and its area.
What is the area of a circle that has a 25 inch diameter?
Calculate the radius, which is simply 1/2 the diameter. Then use the standard formula for the area of a circle. ________________________________________________________________ The circle area = (pi) x diameter / 4 = 3.14 x 25/4 = 19.625 Sq inch
The diameter of the a circle is 2.42 m calculate its area in signicicant figures?
Area is 4.6 m2
How do you calculate the area of a circle without a radius?
Use the diameter and divide it by two.
How do you calculate circumference and area of pi?
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
