Multiply the diameter by the value of Pi - and you'll have your answer !
8cm. The radius is always half the diameter.
i don't know i think you should just try your best
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.
The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.
The diameter would be 8cm, because the diameter is always double the radius. That's why the formula 2'Pi'r is also known as 'Pi'd.
It depends on the ratio of what of the circle? Its circumference, diameter, area?
To find the diameter of a circle with an 8cm circumference, you can use the formula C = πd, where C is the circumference and d is the diameter. Plugging in the given circumference of 8cm, you get 8 = πd. To solve for d, divide both sides by π, giving you d = 8/π. Therefore, the diameter of a circle with an 8cm circumference is approximately 2.55cm.
Circumference of a circle = 3.14 x d 3.14 x 8 = 25.12 Therefore the circumference of a circle with the diameter of 8cm is 25.12cm.
C = ~25.133 cm
Area of a circle = pi*radius2
radius=4cm diameter=8cm *radius is half the diameter
The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
Area of any circle = pi*radius squared
8cm. The radius is always half the diameter.
the answer is 20.54
A = 5.093 cm2
The diameter of a circle is twice its radius. If the radius is 8 cm, the diameter can be calculated by multiplying the radius by 2. Therefore, the diameter is 8 cm × 2 = 16 cm.
