What is the circumference of a pool if the radius is 5m?
Multiply the radius by 2, then multiply that result by the value of Pi - and you'll have your answer.
How do you get the diameter from the radius?
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
To get the volume of a multiply pi by the radius squared and then multiply by the height.?
That is correct for finding the volume of a cylinder.
How do you find the area of circles if you have the diameter?
you take the diameter and divide it in half then you have the radius. Take the radius and multiply the radius by its self (radius squared) then multiply by 3.14 (pi) example: Diameter is 24 find the area. 24 divided by 2 is 12 12x12= 144 144x3.14= 452.16
Find the circumference of 15cm radus circle?
15mm what? Diameter or radius? Formula for finding Circumference is Pi X Diameter. If 15mm is the Diameter, multiply 15mm by 3,1614 = 47.124mm. If 15mm is Radius, then multiply Radius by 2 to get Diameter and then multiply by 3.1416 = 15 X 2 = 30 X 3.1416 = 94.248mm.
How do you convert radius into perimeter?
Multiply the radius by itself, then multiply the result by Pi.
What is the radius of a circle if the circumference is 6?
you simply multiply the radius by 2 and multiply that by 3.14159
How do you find circumfrerence if you know the radius?
Multiply the radius by 2 and multiply the result by 3.141592654....(pi)
What does it mean to square the radius?
It means to multiply the radius by itself: radius x radius
How do you change a radius to a diameter?
Multiply the radius by 2.
How do triple the radius?
Multiply the radius by the integer 3.
How do you find the diameter of a radius?
Multiply the radius 2x to get you answer. Example: Say your radius is 4. You multiply that by 2 (4 x 2 = 8)
How do you find the circmference if you know the radius?
double the radius or multiply by 2 the radius
Find the circumference of a circle when given the radius?
You multiply the radius by 2. Then you multiply the product by pi (3.14)
Do you multiply the 4 numbers and get the diameter?
No you don't multiply the 4 numbers you take radius times radius
If you have radius how do you find diameter of circle?
Multiply the radius by 2.
Do you have to multiply when doing area?
That depends what data you are given. If you have linear measurements, you'll somehow have to multiply them. For example, for a rectangle, you multiply length x width; for a circle (if you know the radius) you multiply pi x radius x radius, etc.
