The perimeter of a circle is calculated using the equation Pi x D = 3.14 x 5 = 15.7cm
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.

10 cm
Oh, what a happy little question! If the diameter of a circle is 10 cm, we can find the radius by simply dividing the diameter by 2. So, the radius would be 5 cm. Just imagine that circle sitting there, perfectly balanced and ready for some happy little trees.
A circle of radius 10cm has a circumference of 2πr cm = 2π x 10 = 62.83 cmIf the diameter equalled 10cm then the radius equalled 5 cm and the circumference of this circle = 2π x 5 = 31.42 cm
cicumference = pi*5 cm area = pi*2.52 square cm
Perimeter = diameter x pi. Area = pi x radius2. (The radius is half the diameter.)
The straight edge of the semicircle is the diameter, which measures 10 cm. The radius is half of the diameter, so it is 5 cm. The perimeter of the semicircle includes the curved part plus the diameter: the curved length is (\pi \times r), which is (\pi \times 5 = 5\pi) cm. Therefore, the total perimeter is (5\pi + 10) cm, approximately (10 + 15.71 = 25.71) cm.
10 cm; the diameter of a circle is twice its radius.

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.
10 cm (diameter is double the radius)
5 cm
it is half the diameter e.g 10cm diameter = 5 cm radius
The circumference of a circle can be calculated using the formula ( C = \pi d ), where ( d ) is the diameter. For a circle with a diameter of 5 cm, the circumference would be ( C = \pi \times 5 \approx 15.71 ) cm. Therefore, the circumference is approximately 15.71 cm.
If the diameter of the circle is 5 cm then its circumference is: 5*pi cm
