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
What are ways a circle graph could be misleading?
Here are two main ways:Represent a single circle graph as a 3-D image. If there are two sectors of the same size, with one at the front of the graph and other at the back, then because of the way in which the brain interprets distance, the sector at the back is judged as being bigger than the one in front.If two (or more) graphs are used to show changes in the composition of different totals: for example populations within age-bands in two countries it is normal to select the sizes (areas) of the circles to represent the totals. However, most people are unable to visually convert a circle with a radius which is 1.42 (approx) times as large as representing a doubling of the area.
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.
How do you calculate the diameter or radius of each circle?
Using the Circumference And Area.
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
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.
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.
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
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
