What else can I help you with?
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 shapes contains a circle?
another, larger circle, perhaps. or a larger shape than the circle.
How do you draw concentric circles?
Leave the point of your compass in the same spot on your paper. Draw one circle, then change the angle to be either larger and smaller, then draw another circle.
How do you find the gap of one cirlcle in a larger circle?
Find the area of both circles (A = πr2) and subtract the area of the larger circle from that of the smaller circle inside it.
How can you find minimum and maximum diameters?
-- Every circle has a diameter of some size. -- All of the diameters that you can draw in the same circle are the same size. -- The smaller the circle is, the smaller its diameter is. There's no minimum size. -- The larger the circle is, the larger its diameter is. There's no maximum size.

Is a smaller circle or larger circle easier?
depending on the circles equation..a larger circle is easier
How do you find area of a circle with another circle in it?
First find the area of the larger circle and then subtract the area of the smaller circle. Area=(pi x radiuslarger)-( pi x radiussmaller)
What shapes contains a circle?
another, larger circle, perhaps. or a larger shape than the circle.
How do you find the area of a smaller circle if a larger be is 48 square feet?
You cannot because you do not know how the circles are related to one another.
How do you draw concentric circles?
Leave the point of your compass in the same spot on your paper. Draw one circle, then change the angle to be either larger and smaller, then draw another circle.
How do you find the gap of one cirlcle in a larger circle?
Find the area of both circles (A = πr2) and subtract the area of the larger circle from that of the smaller circle inside it.
How do you find the percent increase from one number to another?
-- divide the larger number by the smaller one-- subtract '1' from the answer-- multiply what's left by 100You now have the percentage increase from the smaller number to the larger one.
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)
How do you find what percent one number is of another?
divide the smaller number by the larger number, and multiply by 100. 60 is 75% of 80.
How can you find minimum and maximum diameters?
-- Every circle has a diameter of some size. -- All of the diameters that you can draw in the same circle are the same size. -- The smaller the circle is, the smaller its diameter is. There's no minimum size. -- The larger the circle is, the larger its diameter is. There's no maximum size.
