If the radius of a circle is 4 cm what's the diameter?
8cm. The radius is always half the diameter.
How do you draw an octagon on a circle that has a diameter of 8cm?
i don't know i think you should just try your best
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.
Diameter of a circle is 16cm what is the radius?
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.
What is the area of a circle if it has a diameter of 2cm?
The area of a circle with a diameter of two cm is about 3.1416 cm.
What is the ratio of a circle with a radius of 8cm?
It depends on the ratio of what of the circle? Its circumference, diameter, area?
What is the diameter of a 8cm circumference?
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.
What is the circumference of a circle with diameter 8cm?
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.
What is the circumference of a circle with a diameter of 8cm?
C = ~25.133 cm
How do you find the area of a circle if the circle is 8cm?
Area of a circle = pi*radius2
What is the surface area of a cylinder with a height of 8cm and diameter of 10cm?
The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
What is the diameter of a circle whose radius is 4cm?
radius=4cm diameter=8cm *radius is half the diameter
What is the area of a 8cm circle?
Area of any circle = pi*radius squared
If the radius of a circle is 4 cm what's the diameter?
8cm. The radius is always half the diameter.
What is the area of a circle with a circumference of 8cm?
A = 5.093 cm2
What is the area and circumference of a circle with a radius of 8cm?
