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
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 circumference of a circle with diameter 18cm?
18 pi cm
If the radius of a circle is 2cm what is the diameter?
Diameter of circle = 2 * Radius of the circle.
If the Diameter of a circle is 120 what is the radius?
Since diameter is twice its radius, the radius of this circle would be 60
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
What is the radius of 18cm?
The radius of a circle is half of its diameter. If the diameter is 18 cm, then the radius would be 18 cm divided by 2, which equals 9 cm. Thus, the radius is 9 cm.
What is the area of a circle if the radius is 18cm?
Using 3.14 as Pi the area of circle is: 1017.36
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 radius if the diameter is 18cm?
radius = 18/2 = 9 cm
What is the area of a circle that has a radius of 18cm?
1,017.9 cm2
What is the area of a circle with an 18cm diameter?
A = 254.47 cm2
What is the circumference of a circle with diameter 18cm?
18 pi cm
When the diameter of a circle is 85.4 What is the radius of the circle?
The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
What is the radius of a circle if the diameter is 14in?
The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.
What is the radius of a circle with a 6inches diameter?
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
Is diameter of a circle is the length of the radius?
The diameter of a circle is twice its radius.
