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.
R2 - 16 = 0 R2 = 16 Take the square root of each side to get rid of the square on R. R = 4
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.
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

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!
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
Depends on what kind of shape it is. Circle pi*R² Triangle Square/2
2(pi r square)+(2 pi r)*h
No. For a volume you must have a cubic function.
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!
