False.
If you do this you will find the circumference (2 x radius x pi).
Area = 3.14 times (radius squared)

Do you multiply to get perimeter?
No, you add up all the sides. Yes, in terms of a circle. To determine the perimeter or circumference of a circle, you must multiply: 2πr or two times Pi times the radius of the circle.
How you find the diameter if you are given the radius?
What you would do is just multiply the radius by 2 because radius is 1/2 of the diameter.Example:A circle has a radius of 8 cm. What is the diameter?Just multiply 8 times 2 = 16The diameter of the circle is 16 cm.
How do you find the diameter?
The diameter of a circle is the length of a straight line drawn through the center of the circle to its edges.Or, measure the circumference of the circle and divide by pi (3.14159).Or you can multiply the radius times twoTo get diameter you have to find the radius and then double it to get the diameter
How do you find the diameter if you have the area of a circle?
Since the area of a circle is (Pi)times(Radius squared) then you would reverse the process to find the radius, and hence, the diameter. Divide the area by Pi (3.14159...) and you would have the radius squared. Take the square root of that and you have the radius. To get the diameter, multiply the radius by 2.
Why is the circumference of a circle diameter times pi or 2 radius times pi?
Because 2 times the radius is equal to the diameter of the circle
How do you find out the circumfrance of a circle?
To find the circumfrance of a circle, you need to multiply 2 times pi, times the circle's radius. If you don't know what that is, you multiply two times pi, and pi equals 3.14, and then multiply that by the radius, which is the measurement of half the circl'e diameter. the diameter is the distance from one side of the circle, to the exact opposite. you measure this with a ruler. HALF the measurement of the diameter is the radius. Example---the diameter of a circle is 20 cm. half the diameter is 10 cm, which is the radius. Multiply 2 times pi[which equals 3.14], times the radius. Good luck!
What is the diameter d of a circle of radius 13.8 cm?
The diameter is twice the radius (that is, multiply the radius times 2).
How do yo figure out the circumference of a circle?
First, you do the radius of a circle times two. Then you multiply that times PI, which is 3.14.
How do you find area in a circle?
MULTIPLY THE DIAMETER TIMES PI(3.14) OR MULTIPLY THE RADIUS TIMES 2 TIMES PI(3.14).
How do you find the area of a circle by only knowing the radius?
Since the area of a circle is pi times radius squared, take the radius and square it. Then, multiply that by 3.14, or pi to get the area of the circle.
Why do you find the area of a circle with pi times the radius squared?
You find the area of a circle with pi times radius squared because the radius is half the circle so to find the full area you need to multiply it again.
Do you multiply to get perimeter?
No, you add up all the sides. Yes, in terms of a circle. To determine the perimeter or circumference of a circle, you must multiply: 2πr or two times Pi times the radius of the circle.
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.
How you find the diameter if you are given the radius?
What you would do is just multiply the radius by 2 because radius is 1/2 of the diameter.Example:A circle has a radius of 8 cm. What is the diameter?Just multiply 8 times 2 = 16The diameter of the circle is 16 cm.
To find the area of a circle multiply 2 times 3.14 by the radius?
No, that process gives you the circumference of the circle.To find the area of a circle, multiply 3.14 by the square of the radius.Notes:1). The square of the radius means (radius) times (radius).2). The number "3.14" is not exact. It's an approximation for the number "pi".
What is the circumference of the circle roundto the nearest whole number?
-- Multiply (pi) by (diameter of circle)OR-- Multiply (pi) by (2 times radius of circle)-- Then round the product to the nearest whole number.
How do you find the area of circle?
The area of a circle is пr² where r is the radius, or half of the diameter. п is approximately 3.14.
