What is the radius of a sunflower with a circumference of 46 cm?
The formula is: circumference = 2 x pi x radius. As always when you use a formula, plug in the values you know and solve for the ones you don't. So plug in 46 for the circumference and solve for the radius. (You'll get that the radius = (circumference)/(2pi)).
How do you get the radius of a circle from the circumfrance?
To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159

-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.
How do you solve for revolutions per second give centripetal force and radius?
You can solve for revolutions per second using the equation (f = \frac{v^2}{r}), where (f) is centripetal force, (v) is linear velocity, and (r) is radius. Once you know linear velocity, you can calculate revolutions per second by dividing linear velocity by the circumference of the circular path.
How do you find the surface area of a sphere when its volume is 523.5987756 cubic cm?
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
How do you find the radius when you only have area of a circle?
Use the formula area = pi x radius2. If you replace everything you know, you can solve for the radius.

If the area is 628 what is the radius of a circle?
To find the radius of a circle with a given area of 628, you can use the formula for the area of a circle, A = πr^2, where A is the area and r is the radius. Rearranging the formula to solve for the radius, you get r = √(A/π). Substituting the given area of 628 into the formula, you get r = √(628/π) ≈ √(199.87) ≈ 14.14. Therefore, the radius of the circle is approximately 14.14 units.
