How do you find the circumfrence of a circle when you have the area?
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
What is the formula of finding the area of a circle?
Pi * R squared, where R is the radius of the circle in question
How many square inches are there in a 1 inch circle?
Assuming that 1inch is your diameter, your radius is, of course, 0.5. Since the area of a circle is expressed asA=(pi)r2simply plug in the radius to this equation. You will get your area to be pi*0.25in2, which is roughly equal to 0.78539inches2.
How do you calculate areas to 1 decimal place for a circle?
The area of a circle is calculated by multiplying pi by r2. Where r = the radius of the circle. IF we use 3.1416 as our value of pi, this means that a circle with a radius of 1 inch has an area of 3.1416 square inches. Rounding this to one decimal place gives us 3.1 square inches. Other radius - area ratios are 2 .......... 12.5665 - rounded = 12.6 3 .......... 28.2744 - rounded = 28.3 4 .......... 50.2656 - rounded = 50.3 5 .......... 78.54 - - - rounded = 78.5 6 ......... 113.0976 - rounded = 113.1 7 ......... 153.9384 - rounded = 153.9 8 ......... 201.0624 - rounded = 201.1 9 ......... 254.4696 - rounded = 254.5 10 ....... 314.16 - - - rounded = 314.2
Formula for area of cone?
Curved surface area of a cone = pi*radius*slant length
Is the radius of a circle a function of its area?
You can certainly express the radius as a function of its area, yes. If the area is known, you can solve the formula for the area of the circle to uniquely get the radius. (The quadratic equation has two solutions; you will of course choose the positive solution for the radius.)
How do you express the area of a circle as a function of its radius?
If a circle has radius r, then the area of the circle is pi r2, pi being about 3.14159. I beleive the function you are looking for is A(c)=c/2*r
Express in terms of the area of a circle whose radius is 6?
A circle with a radius of 6 units has an area of 113.1 square units.
What is the area of a circle if the radius is 9m?

What is the radius of a circle with the area of 36?
The radius of a circle with the area of 36 is 3.385
What is the area of a circle with the radius of 21?
The area of a circle of radius 21 is 1386
What is the area of circle with a radius of 35?
Area of a circle = pi*radius squared
What is the area of a circle with the radius of 14.4?

What is the area of a circle of the radius of 10m?
A circle with a radius of 10m has an area of 314.16 m2
What is the area of a circle with radius of 2m?
The area of a circle with a radius of 2m is: 12.566 m2
