How to transtar sector 10?
sector 10-1 double 270 degrees then reflect it idk the others
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 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 inches if the length of the arc is 10 inches?
The area of the full circle is (pi R2) = (25 pi) square inches. The full circumference is (2 pi R) = (10 pi) inches. An arc length of 10 is [ 10/(10 pi) ] = ( 1 / pi ) of the full circle. So the area of the sector is (full area / pi) = (25 pi) / pi = 25 square inches
How do you find the area of a 72 sector of a circle whose radius is 10 cm?
A 72 degree sector represents 72/360 = 1/5 of a circle. Area of whole circle = pi*r2 = 100*pi So area of 1/5 circle = 20*pi = 62.83 cm2 (approx).
