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
A circle has a diameter of 10 cm what is the radius?
the radius of a circle is half of its diameter.
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.)
If the diameter of a circle is 20 centimeters what is the radius of the circle?
10 cm
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 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 semi circle has a diameter of 10 cm the perimeter is 25 point 7 rounded how do you get that answer?
half times pi times 10....
What is the radius and diameter of a circle 10-cm?
radius 5 cm diameter 10 cm
What is the diameter of a circle with the radius of 5 cm?
10 cm; the diameter of a circle is twice its radius.
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)
The radius of a circle is 5 cm which is the diameter of the circle?
10 cm
What is the area of a circle whose diameter is 10 cm?
The area of a circle whose diameter is 10 cm is: 78.54 cm2
A circle has a diameter of 10 cm what is the radius?
the radius of a circle is half of its diameter.
What is the radius of a circle that has a 10 cm diameter?
The radius of a circle is half the length of its diameter. Therefore, if the diameter of the circle is 10 cm, the radius would be half of that, which is 5 cm. The formula to find the radius of a circle is r = d/2, where r is the radius and d is the diameter.
