If a circumference of a circle is 10pi What is the radius of a circle?
The radius of the circle works out as 5 units in length
What is the circumference of a circle with a 5 inch radius?
10pi, ie 31.415 inches.
In circle O the area of the sector with central angle AOB is 30 pi cm squared and radius OA is 6 cm. What is the angle measure of arc AB and the length of AB?
The area of the whole circle is PI x 6 squared which equals 36 PI. We can now use the ratio 30/36 = x/360 to find the angle (360 is the full angle if the circle, x is the angle of the segment, pi's cancell out) If we solve for x we get 300 degrees which is the angle we need. As for the length, the circles circumference is 12 PI (12 is the diameter). This means that 30/36= AB/12PI AB=10PI
If a circumference of a circle is 10pi What is the radius of a circle?
The radius of the circle works out as 5 units in length
If the circumference of a circle is 10pi then what is the radius of the circle?
The radius of the circle works out as 5 units
What is the circumference of a circle with a 5in radius?
10pi
What is the area of a sector of a circle which has a diameter of 10 inches if the length of the arc is 10 inches?
diameter d = 10 in radius r = 5 in arc length s = 10 in C = pi d = pi x 10 in = 10pi in s/C = 10 in/10pi in = 1/pi A circle = pi r2 = pi(5 in)2 = 25pi in2 A sector/A circle = 1/pi (cross multiply) pi A sector = 25pi in2 (divide both sides by pi) A sector = 25 in2
What is the area of a sector of a circle that has a diameter of 10 in. if the length of the arc is 10 in.?
The sector area works out as: 10/10pi times 25pi = 25 square in.
What is the circumference of a circle whose radius is 5 ft?
10pi= 31.41592...
What is the circumference of a circle with a 5 inch radius?
10pi, ie 31.415 inches.
What is the radius if a circle is 5 cm Estimate the circumference?
I'm not sure what you mean. If the radius is 5, the circumference is 10pi. (about 31 and a half) If the circumference is 5, the radius is 5 divided by 2pi. (about four fifths)

As for the length, the circles circumference is 12 PI (12 is the diameter). This means that 30/36= AB/12PI AB=10PI
What is the measure of the central angle of a circle with radius 5 m that intercepts a 2 m arc?
It is: 2/10pi times 360 = 23 degrees rounded Or, more simply, it is 2/5 = 0.4 radians.
If the length of the minute hand of a clock is 5cm how can you calculate its speed?
The minute hand traces its path around the clock once in an hour. The distance travelled by the tip of the hand in this time is 2 x pi x 5cm.The speed is then 10pi cm/hour, which is 8.73 x 10-5 ms-1.
