What is the approximate area of a circle with a radius of 3 feet?
Area of a circle equals pi (~3.14) multiplied by the radius squared. So to find the area of that circle your equation is (3.14)(3)^2 which equals approximately 27.
Find the center and radius of the circle with this equation X2 plus Y2 minus 6X plus 2Y equals 0?
The centre is (3,-1) and the radius is sqrt(10).
Which equation could be used to find the circumference of a ball with a radius of 5 inches?
The circumference of a circle equals 2 times pi times the radius, in this case, about 31.42 inches.
How do you find the radius of the circle if you know the area?
Area of a circle equals pi r2 Therefore the radius of a circle equals the square root of (area divided by pi).
How do you find the radius of an inscribed circle of a square given the area of the square?
Half the square root of the square radius equals the circle radius.
What is the approximate area of a circle with a radius of 3 feet?
Area of a circle equals pi (~3.14) multiplied by the radius squared. So to find the area of that circle your equation is (3.14)(3)^2 which equals approximately 27.
The equation of the inner circle is x2 plus y2 equals 4 the radius of the outer circle is four times the radius of the inner circle write the equation of the outer circle?
The inner circle is x2 + y2 = 4. The radius of the inner circle is the square root of 4, which is 2. To find the radius of the outer circle, multiply 2 times 4. The radius of the outer circle is 8. Square 8 (82 or 8 x 8) to find the number to put into the equation of the outer circle. This is 64. The equation for the outer circle is x2 + y2 = 64.
Find the radius of a circle with the equation x2 plus y2 equals 16?
x2 +y2 = R2 =16 = radius 2 R = 4
Find the radius for a circle with the equation x2 plus y2 equals 25?
x^2 + y^2 = r^2
Find the center and radius of the circle with this equation X2 plus Y2 minus 6X plus 2Y equals 0?
The centre is (3,-1) and the radius is sqrt(10).

The circumference of a circle equals 2 times pi times the radius, in this case, about 31.42 inches.
How do you find the radius of the circle if you know the area?
Area of a circle equals pi r2 Therefore the radius of a circle equals the square root of (area divided by pi).
How do you find the radius of circle with area 144pi?
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
How do you find the radius of an inscribed circle of a square given the area of the square?
Half the square root of the square radius equals the circle radius.
Find the center and radius of the circle with this equation x2 plus y2 plus x equals 0?
x2+y2+4x+2y+3=0(x+2)2 + (Y+2.5)2 = 3This is the equation of circle with center at (-2,-2.5) with radius 3.5
When you are given pi of a circle how do you find the radius and diameter?
you cant: pi is the same for any circle - 3.1415... the diamter or the radius has to be given diameter divided by two equals the radius the radius times two equals the diameter
The diameter equals 18cm how do I find the area?
The general equation for the area of a circle is π*r2, where r is the radius of the circle, and π is pi, which is approximately 3.14159. The diameter of a circle is how far it is from one side of the circle to the other, and the radius is how far it is the from edge to the center, thus the radius is half the diameter. Therefore the area is π*(92) ~ 254.47
