Answer:

36

Step-by-step explanation:

We can make an algebric equation.

2x+3x=90

5x=90

x=18

Since we wanna find the boys, we multiply the boys ratio with our x value.

2x=2•18=<u>36 boys</u>

Circle O is shown. Line segments B O and O C are radii. Point A is on the circle and is not within angle B O C.

The ratio of major to minor arc = 2 : 1

What is a Circle?

A circle is the locus of a point such that its distance from a fixed point (center) is always constant.

Calculation

The length of an arc (L) with center angle θ is given by:

                                          L = (θ/360) * 2πr

where r is the radius.

Putting the values in the above formula.

For the major arc:

L = (240/360) * 2πr

For the major arc:

l = ((360-240)/360) * 2πr

l = (120/360) * 2πr

The ratio of major to minor arc = [(240/360) * 2πr] / [(120/360) *2πr] = 2 : 1

The ratio of major to minor arc = 2 : 1.
