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.
If the radius of a circle is 4 cm then what is the diameter?
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.
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 diameter of a circle whose radius is 4cm?
radius=4cm diameter=8cm *radius is half the diameter
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 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?
the answer is 20.54
If the radius of a circle is 8cm what is its diameter?
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.
