What is the area of a circle if the radius is 18cm?
Using 3.14 as Pi the area of circle is: 1017.36
What is the radius with a circle with a diameter of 18cm?
9 cm (r = d/2)
The diameter equals 18cm how do I find the area?
The general equation for the area of a circle is π*r2, where r is the radius of the circle, and π is pi, which is approximately 3.14159. The diameter of a circle is how far it is from one side of the circle to the other, and the radius is how far it is the from edge to the center, thus the radius is half the diameter. Therefore the area is π*(92) ~ 254.47
What is the area of a circle with an 18cm diameter?
A = 254.47 cm2
What is the perimiter of a semi circle if the radius is 18cm?
The perimeter is pi*r + 2r = 92.6 cm
If a circle has a radius of 9 cm how long is the circle's diameter?
The diameter is always double the radius so in this case, it is 18cm
