What is pi times r2?
pi times radius or diameter equals are of a cirlce
What is the radius If the circumference is 96.5?
C = pi times 2 radius or radius = C / (pi times 2) = 96.5 / (3.14 times 2) = 96.5 / 6.28 = 15.37
Is the circumference greater than the diameter?
No. Circumfrence=2 times pi times radius. And since the daimeter = 2 times radius, circumference is diameter times pi.
How do you find the diameter of a cylinder from the area of the base?
The area of the base of a cylinder = Pi times Radius squared. Diameter of a cylinder = 2 times Pi times Radius. To find the diameter derive the area of the base by Pi and then square root the answer. That will give you the value of the radius. Multiply that answer by 2 times Pi and you will have your answer.
What is the circumference of 8m radius circle?
Approximately 50.26m, because circumference is equal to diameter times pi (or 3.1415). Or twice the radius times pi.
How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
How do you find the perimeter and area of a circle?
perimeter (circumference): diameter times pi (3.14) area: radius times radius times pi (3.14) Area = pi*radius squared Circumference = 2*pi*radius or pi*diameter
How do you find the circumfrence of a circle with the radius?
two times the radius times pi
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
Is circumfrience pi times radius to the 2?
circumfrience is pi times radius to the 2 i think
Is circumference radius times pi?
NO!!!! C = 2 pi r C = pi d In words ; Circumference equals two times 'pi' times radius or , circumference equals 'pi' times diameter. NB The diameter is twice the radius. Also A = pi r^(2) In words, Area equals 'pi' times the radius squared. Read learn and comit to memory these two circle equations.
How do you get from the radius to the circumference?
(radius+radius) times pi
Surface area of cone?
(pi times radius squared) plus (pi times radius times slant).
How do you find the circumference from the area?
Well, you find the area of a circle by multiplying (pi times radius2) or (pi times radius times radius). The radius is half of the diameter. The formula for the circumference is (pi times diameter). Multiply the radius times 2 to get the diameter. Multiply the diameter times pi.
What is formular of circle?
Area of a circle: pi times radius squared Circumference of a circle: 2 times pi times radius or diameter times pi
Volume of a cone?
Pi times Radius times Radius times height
How can you find the circumference if you have the radius?
Radius times 2. then, that times Pi
