The circle shown below has a diameter of 18 centimeters. What is the area of the shaded sector?
N76 [4]
Area of circle = Pi x r*2

If diameter is 18, radius is 9.

Area = pi (3.14) x r*2 (9*2 = 81) .. 3.14 x 81 = 254.34 sq cen = total area of circle.

A circle is 360 degrees, the shaded area is 270 degrees. the shaded area is 3/4 (270/360) of the area of the circle.

254.34 x 3/4 = 190.755 sq cen

Hope this helps

The corners of a square lie on a circle of diameter d = 0.35 m. each side of the square has a length l. find l.
sergeinik [125]

Refer to the attached image.

As we can observe ABCD is a square, whose corners that is A,B,C and D lie on the circle.

The diameter AC = 0.35 meter.

We have to find the side of square.

Let the measure of side of a square be 'l' meter

In triangle ABC,

By Pythagoras theorem, we get

(AC)^2 = (AB)^2 + (BC)^2

(0.35)^2 = (l)^2 + (l)^2

(0.35)^2 = 2(l)^2

\frac{(0.35)^2}{2} = (l)^2

l^2 = 0.06125

So, l = 0.25 meter

Therefore, the measure of side of the square is 0.25 meter.
