What else can I help you with?
If the area of one circle is four times as large as a smaller circle with radius of 3 inchesThe radius of the larger circle is?
6 inches pi*32 = 9*pi square inches (smaller circle) pi*62 = 36*pi square inches (larger circle)
What is a circumference of a circle with the radius of 9 inches?
A circle with a radius of 9 inches has a circumference of 56.55 inches.
What is the area of a circle if the radius is 32 inches?
A circle with a radius of 32 inches has an area of 3,216.99 square inches.
What is the radius of a circle with circumference 30in?
The radius of a circle with a circumference of 30 inches is: 4.77 inches.
If he radius is 12 inches what is the diameter?
The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
If the area of one circle is four times as large as a smaller circle with radius of 3 inchesThe radius of the larger circle is?
6 inches pi*32 = 9*pi square inches (smaller circle) pi*62 = 36*pi square inches (larger circle)
What is the perimeter of a circle with a radius of 15 inches?
Larger than a whale yet smaller than an ant
What is a circle with a little circle in it called?
An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
In the two circles shown below the radius of the larger circle is three times the radius of the smaller circle If the area of the larger circle is 60.84 timmespi what is the area of the smaller circle?
if the radius is a third then the area is a ninth 60.84 x 1/32 = 6.76 timmespi (if that's 'times pi' then) 6.76/pi = 2.15
The area of one circle is four times as large as a smaller circle with a radius of 3 inches The radius of the larger circle is?
R = radius of big circle, r = radius of little circle Area of circle = pi x R x R = 4 x pi x r x r = 4 x pi x 3 x 3 Therefore R x R = 36 and so R = 6 inches
What A circle with a radius of 3 cm shares a center with another circle that has a radius of 5 cm. Find the probability that a randomly selected point is in the larger circle but not in the smaller ci?
We can look at total areas (and ignore units-they're all the same). The smaller circle has an area of 9pi, and the larger circle has an area of 25pi. The smaller circle is entirely inside of the larger circle. So anything not in the smaller circle is in the larger circle. 16pi square centimeters are part of only the larger circle. 16pi/25pi=.64. So the desired probability is .64.
What is the radius of a circle if its radius is 8 inches?
The radius is 8 inches.

What is the circumference of the circle if the radius 10 inches?
The circumference of a circle with a radius of 10 inches is about 62.83 inches.
If the diameter of the circle is 16 inches what is the radius in inches?
Radius of circle: 16/2 = 8 inches
What is the circumference of a circle with the radius of 4.246 inches?
