Find the area and perimeter of a given circle?
If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
How do you calculate the perimeter of a circle?
The perimeter or circumference of a circle = 2*pi*radius or pi*diameter
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
A straight line from the center to the perimeter of a circle?
Its radius.
Find the area and perimeter of a given circle?
If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
How do you find the perimeter of a circle if you know the radius?
2 x Pi x radius = circumference
How do you find the radius of a circle if you know the perimeter?
you can divide the perimeter(circumference) by pi(3.14) and then once you get your answer you divide that by two giving you the length of the radius of the circle. ex: perimeter = 34pi 34pi/pi 34/2=diameter 16=radius
How do you find the circumfrence of a circle if you have the radius?
the circumfrence of a circle is pi times it's radius squared.
How do you find the perimeter of a shape that has a semicircle?
To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.
What is the formula for finding the radius of a circle when you have the perimeter?
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
How you find the perimeter of quadrant?
If you the radius of the circle is r then the perimeter of a quadrant = r*(2 + pi/2).
How do you find the perimeter of a half circle?
Let r be the radius of the circle. Then the perimeter of the half circle is pi*r + 2r. That is half of the circumference plus the diameter.
How to find area and perimeter of circle?
The answer depends on what information you have about the circle. If you know the radius, thenArea = pi*r^2 and perimeter = 2*pi*r
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
Is the radius the measurement of the perimeter of a circle?
No.
How do you find the perimeter of the circle of radius r?
by using formula 2. pie. r
