Area of a circle is 36 square centimeters what is the circumference of the circle?
The area of a circle with radius r is pi*r*r and its circumference is 2*pi*r Use the first to find r and then use that value of r in the second to find the circumference.
What is the value of R in R squared -16 equals 0?
R2 - 16 = 0 R2 = 16 Take the square root of each side to get rid of the square on R. R = 4
What if the number is unknown to find square root square root?
It is no tpossible to find the square root of an unknown number. You can, however, represent it as x0.5 or √x so that the value of the square root can be evaluated when the value of x is known.
How do you find perimeter of a square inscribes in a circle?
one side of the square inscribed in a circle of radius r is sqrt2 * r (the square root of two times the radius) So the perimeter is 4 * sqrt2 * r
O is the center of the sector oab CD is another arc with center o and radius r cm DB equals 2cm if the area of abcd is one-third the area of the sector OCD find the value of r?

What is the circumference with a area of 201 square inches?
Since you say circumference, the area must be that of a circle. The area of a circle is pi x r x r where r is the radius. So we have 201 = 3.1415 x r x r Therefore r = square root of (201/3.1415) Find this. I am sure you can. Once you have r, the circumference of the circle is 2 x pi x r So plug in the value of r obtained before in 2 x 3.1415 x r and you have the answer. You can do it. Good luck!
If the area is 75mm what is the radius?
area= Pi x r-squared (25) divided by 3.14 = (3.14 x r-squared) divided by 3.14 (7.96) find the square root = (r-squared) find the square root 1.4 = radius
How do you find the square feet of a non square shape?
Depends on what kind of shape it is. Circle pi*R² Triangle Square/2
Can you use r square to find the volume of sphere inside of r cube?
No. For a volume you must have a cubic function.
How do you find the total surface area of a cylinder?
2(pi r square)+(2 pi r)*h
How do you find the radius and theta only knowing the arc length and area?
A=pi*r^2, so to find the radius, divide the area by pi and take the square root of that quotient. theta/360=arc length/circumference. C=2pi*r, so multiply the radius you found above by 2pi. Then you have theta/(known value)=(known value)/(known value), so you can now solve for theta!
