If the radius of a circle is 5 cm what is the diameter?
if a radius is 5cm the diameter is 10cm rule- you double the radius
How do you find volume of a circle?
A circle has no volume; it is a 2D shape. If you mean a sphere, then the formula is V = (4/3)πr3 where V is volume, π is pi (~3.14) and r is radius.
What is the diameter of a circle if the radius is 4 units?
8 units; the diameter of a circle is twice its radius.
If the radius of a circle is 4 cm what is the area of the circle?
4 cm radius = Area of 50.26548 sq. cm.
If the diameter of a circle is 4 centimeters what is the length of the radius?
Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
Radius equals 4 what will be the area of circle of this radius?
A = 50.27 square units.
The equation of a circle centered at the origin is x2 plus y2 16. What is the radius of the circle?
If that equals 16 then the radius is 4
X2 plus y2 equals 16 radius of the circle?
4
What is the volume of a cylinder if the radius equals 4 and length is 12?
The volume of the cylinder is 603.186
HOW TO find the volume of a circle?
The area of a circle is 'pi' multiplied by the square of the circle's radius.The volume of a circle is zero.The volume of a sphere is (4/3 pi) multiplied by the cube of the sphere's radius.
What is the formula for finding the radius of a circle when you have the volume?
If by circle you mean sphere, then the volume of a sphere is: 4/3 * pi * radius^3. If you already know the volume, then here's what you do: 1. Multiply the volume by 3/4. 2. Divide the volume by pi. 3. Take the cube root of both sides In other words, the formula for radius when volume is known is: ( ( Volume * 3 ) / ( 4 * pi ) ) ^ (1/3)
What is the radius of a circle with diameter of 8inches?
The radius of a circle with diameter or 8 inches is 4 inches. The diameter equals 2 times the radius or d=2*r. --> 8 in = 2*r so, r = 4 in
What is the formula for the volume of a sphere with radius that equals 5?
The formula for the volume of any sphere isVolume = ( 4/3 pi ) x (cube of the radius)
Will a circle with a radius of 4 inches fit inside a circle with a diameter of 5 inches?
no because the radius is half the diameter so it must be multiplied by two in order to find the diameter of that circle which is 4 times 4 equals to 8 so the circle which has a diameter of 5 inches is much to small for a circle with a radius of 4 inches to fit.
How do you calculate the volume of a circle?
Circles do not have volume because they are 2 dimensional. The area of a circle is PI*r2 . A sphere has volume and the volume of a sphere is 4/3*pi*r3 where r is the radius.
Formulas with include pi?
Area of a circle: pi*radius^2 Circumference of a circle: 2*pi*radius or diameter*pi Volume of a sphere: 4/3*pi*radius^3 Surface area of a sphere: 4*pi*radius^2
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.
