How do you find the radius with the circumference and area having the same value?

Please note that a circumference is a linear measurement (for example, meters), while area is an area measurement (for example, square meters), so the "equality" depends on the units used.
Anyway, all you need to do is write the expression for the circumference, and the expression for the area, then put an equal sign in between - since the problem states that the two are equal. Then solve this equation.

Can the area and the circumference of a circle have the same value?
They can't have the same value, since area has square units and circumference has linear units. But their number portions can be the same. The circumference and the area of a circle with a radius of 2 are both (4 pi), with the appropriate units.
How do you find the circumference and area with a radius of 15 inches?
The circumference is found by doubling the radius, and multiplying that number by the value of PI. The formula is Pi x 2rThe area is found by squaring the radius, then multiplying that number by the value of Pi. The formula is Pi x r2 The letter r in both cases represents the radius.
If the circumference of a circle is increased by 50 then the area will be increased by?
there is no constant that will calculate this, since circumference is calculated with only radius and area with radius squared. you will have to calculate the radius using the initial circumference and then the radius again for the new circumference (with the 50 added). then calculate an area for each radius..then you can see the increase.
How can I find circumference when only area is given?
Radius = square root of (area/pi) Circumference = 2*pi*radius
What is the circumference and the area of a circle with a radius of 3?
28.26=area 18.84=circumference
What is the radius of a circle that has a circumference with the same numerical value as its area?
1
What is the area and circumference of 30.5meters using 3.14 having a solution?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
What is the value for the circumference of 3 ft?
It depends on what you require the value of: radius, diameter, area, for example.
How do you find the area of a circle if you know the circumference?
Circumference = pi x diameter = pi x 2 x Radius (By definition - Step 1) So Radius = (Circumference)/(pi x 2), (find Radius - Step 2) Area = pi x Radius x Radius, (substitute value or radius obtained in step 2)
How do you find the circumference with no radius or diameter?
They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi

What is the radius and area of a circle if the circumference is 157?
The radius and area of a circle if the circumference is 157 are:r = 25A = 1,960
How do you find circumference and area of a circle if radius is known?
Circumference = 2*pi*radius Area = pi*radius2
How do you get circumference from area of a circle?
Area = π × radius² → radius² = area/π → radius = √(area/π) Circumference = 2 × π × radius = 2 × π × √(area/π) = √(2² × π² × area/π) = √(4 × π × area)
What is the circumference and the area of a circle with a radius of 3?
28.26=area 18.84=circumference
