We know that the circumference of a circle is equal to the diameter times pi- or 3.14. With a quarter circle, we know the Radius- distance from the center point to the edge. Double that, and you have the diameter of a whole circle. Multiply that by pi, and you have the circumference of the whole circle- but since you have a quarter circle, divide that by 4. A 3 ft quarter- times 2= 6. 6x3.14= 18.84. divide THAT by 4=4.71. NOW add in the original radius for each of the two STRAIGHT sides- that is 3 x 2, or 6, PLUS the length of the curved part- 4.71, and you have 10.71 ft. So you have the length of the two straight sides, and the curving 3rd side combined.

What is the perimeter of quarter circle?
The arc is one quarter of a circle so is 2pir, the other components of the quarter circle are the two radii, so perimeter is 2r+2pir = 2r(1+pi)
What is the perimeter of a three quarter circle?
Oh, dude, the perimeter of a three quarter circle is basically the same as the circumference of a full circle minus a quarter of it. So, you just take the formula for the circumference of a circle (2πr) and multiply it by 3/4. Easy peasy, lemon squeezy!
How do you find the diameter of a circle with the perimeter?
The equivalent of a "perimeter" in a circle is actually called its circumference. To get the diameter, just divide the circumference by pi.
How do you find the perimeter of a rectangle with a semi circle attached to it?
add the perimeter of the rectangle, minus the side that'c covered by the semi circle. then, find the circumference of the semi circle [diameter x pi, divided by 2] and addd them together
Can you give me a figure to find the perimeter?
Perimeter of what? A circle diameter times Pi. Another shape the sum of all sides.
What is the perimeter of quarter circle?
The arc is one quarter of a circle so is 2pir, the other components of the quarter circle are the two radii, so perimeter is 2r+2pir = 2r(1+pi)
What is the perimeter of a three quarter circle?

What is the equation to find the perimeter of a circle?
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
How do you find the perimeter if you already know the circumference of a circle?
The circumference of a circle is the length of the circle's perimeter.
How do you find the perimeter when circumference is given?
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
What is the quarter circle's radius if the perimeter of a quarter circle is 32.13 centimeters?
The perimeter of a quarter circle is 2 radii plus a quarter of the circumference of the whole circle: → 2 × radius + ¼ × 2 × π × radius = 32.13 cm → radius × (2 + π/2) = 32.13 cm → radius = 32.13 ÷ (2 + π/2) cm ≈ 9.00 cm
What is the formula of a perimeter of a circle?
to find the perimeter of a circle you simply do this (pi x D )
How it will come the perimeter of a quarter circle?
It is a 90 degree turn or circumference/4
What is the perimeter of a rectangle that is 20cm by 2cm which has a quarter circle of radius 11cm on one 20cm side running off the 2cm side using 3.14 for π?
Normally, the amount of the side of the rectangle below the quarter circle on it would expected to be calculated. However, the radius of the circle equals the amount that is subtracted, but in calculating the perimeter it has to be added back in again as it forms part of the perimeter. Thus the perimeter is the perimeter of the rectangle plus a quarter of the circumference of the circle. → perimeter = 2 × (20cm + 2 cm) + ¼ × 2 × π × 11 cm ≈ 44 cm + 3.14 × 11/2 = 61.27 cm.
Find the area and perimeter of a given circle?

How do you find the perimeter of a semi circle with a diameter of 12mm?
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
How do you find perimeter of half circle?
The formula for the perimeter of a whole circle is 2 π r therefore the perimeter of a half circle will be (2 π r)/2 which is π r n.b. the perimeter of a circle is normally referred to as the circumference...
