What is the correct formula for calculating the circumference of a circle?
[2 x pie x radius] or [pie x diameter]
What is the area of a circle with a radius of 13.25?
Main Answer: To find out the area of the circle you must square the radius. Here's the answer: I took pie as 3.141592 Area = pie x radius squared A = pie x 13.25 squared --> pie x (13.25 x 13.25) A = 551.5457455 Don't forget to put the units on (e.g. mm, cm, etc) and round to whatever number of decimal places this question asks for. Extra Info: Circumference of a circle = pie x diameter Area of a circle = pie x radius squared C herry pie's d elicious --> C = pie x d A pple pie's r 2 --> A = pie x r2
How do you find the value of a?
Lenght x r x pie x 2
What is the volume of a cylinder with a radius of 7 and a height of 4?
Volume of cylinder= pie x 72 x 4 = pie.196 = 616 cubic units.(Taking pie= 22/7)
How do you work out a peace of pie on pie chart?
A sector or piece (not peace!) representing x % of the total has an central angle of 3.6*x degrees.
