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".

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.
How to find area of a circle?
you take the radius and multiply it by itself. then you multiply the radius squared by 3.14 to get the area of a 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 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.
Why do we multiply radius two times it self to get the area of a circle why not diameter?
It's simply because the area of a circle is defined as pi * r * r.
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.
How to find area of a circle?
you take the radius and multiply it by itself. then you multiply the radius squared by 3.14 to get the area of a circle...
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 easily find the area and the circumference of a circle?
Area- square the radius of the circle and multiply it by pi Circm.- multiply the radius by 2 and then multiply that number by pi
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 the circumference and area of a circle that has a radius of 4?
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
What do you multiply the radius by?
circumference of a circle = 2*pi*radius area of a circle = pi*radius squared
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.
What is the formula for the area of the circle?
r2*pi=A π ● r² or pi times the radius squared If you are given the diameter just divide that by 2 giving you the radius. After that square the radius (multiply by it by itself). Then multiply that answer by 3.14 or pi. Area of a circle = pi*radius2
What is the formula for the circumference of a circle from the area?
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
Why do we multiply radius two times it self to get the area of a circle why not diameter?
It's simply because the area of a circle is defined as pi * r * r.
