What is the perimeter of a circle with the radius of 7cm and diameter of 14cm?
The perimeter of a circle is equal to pi times the diameter, so for a circle with a diameter of 14 cm, multiply by pi, which is approximately 3.14, and you get 43.96 cm, which for most purposes you could round off to 44 cm.
A circle has a radius of 8.5cm what is the diameter of the circle?
The radius measures from the center of the circle to the perimeter (outside), so if the radius is 8.5 cm that would make the diameter of the circle 17 cm. (8.5 cm X 2 = 17 cm)
What is the perimeter of a semicircle if the diameter is 8cm?
To find the perimeter of a semicircle, you need to add the curved edge (half the circumference of a full circle) to the diameter of the semicircle. The formula for the circumference of a full circle is C = πd, where d is the diameter. Therefore, the circumference of the full circle is π(8) = 8π cm. The perimeter of the semicircle would be half of the circumference of the full circle plus the diameter, so it would be 4π + 8 cm, or approximately 20.28 cm.
What is perimeter of a circle with a diameter of 50 cm?
50* Pi pi = 3.14159 so 157.08 to 2dp
What is the perimeter of a semicircle with radius 8cm?
A semicircle is half a circle. So the perimeter of a semicircle is half the circumference of the whole circle plus the diameter, which is twice the radius: perimeter = 1/2 x 2{pi}r + 2r perimeter ~= 3.14x8 + 2x8 ~= 41.13cm
Find the perimeter of a circle if the diameter is 36 centimetres?
Perimeter = pi*diameter = 113.1 cm
What is the perimiter of a circle with a diameter of 12cm?
perimeter of a circle = circumference = pi x diameter perimeter = 3.1416 x 12 = 37.7 cm
What is the perimeter of a circle which has a diameter of 10 cm?
In the case of a circle, it is common to call this "circumference" instead of "perimeter". Just multiply the diameter by pi.
What is the perimeter of a circle with the radius of 7cm and diameter of 14cm?
The perimeter of a circle is equal to pi times the diameter, so for a circle with a diameter of 14 cm, multiply by pi, which is approximately 3.14, and you get 43.96 cm, which for most purposes you could round off to 44 cm.
What is the radius of a circle of perimeter 20 cm?
Pi= 3.1416 circle / 3.1416=diameter
A circle has a radius of 8.5cm what is the diameter of the circle?
The radius measures from the center of the circle to the perimeter (outside), so if the radius is 8.5 cm that would make the diameter of the circle 17 cm. (8.5 cm X 2 = 17 cm)
What is the perimeter of a circle with a diameter of 5 cm?
The perimeter of a circle is calculated using the equation Pi x D = 3.14 x 5 = 15.7cm
What is the perimeter of a square in centimeters circumscribing a circle of radius a centimeters?
The side of the square is equal to the diameter of the circle, in this case 2a so the perimeter is 8a cm.
What is the perimeter and area of a circle with diameter equal to 5 cm?
Perimeter = diameter x pi. Area = pi x radius2. (The radius is half the diameter.)
What is the perimeter of a semicircle if the diameter is 8cm?
To find the perimeter of a semicircle, you need to add the curved edge (half the circumference of a full circle) to the diameter of the semicircle. The formula for the circumference of a full circle is C = πd, where d is the diameter. Therefore, the circumference of the full circle is π(8) = 8π cm. The perimeter of the semicircle would be half of the circumference of the full circle plus the diameter, so it would be 4π + 8 cm, or approximately 20.28 cm.
What is the perimeter and area of a circle with diameter equal to 5cm?
cicumference = pi*5 cm area = pi*2.52 square cm
What is perimeter of a circle with a diameter of 50 cm?
50* Pi pi = 3.14159 so 157.08 to 2dp
