Question

Cutting a circle into equal sections of a small central angle to find the area of a circle by using the formula a=r 2

Answer 1

we need to draw a huge circle on a chart paper with unknown radius.Then we need to cut out equal sections of the circle just like how u cut a pizza slice.When u have cut out the whole circle, place each section next to each other by alternately placing in opposite direction.Now u'll get a line of these sections.Measure the length of it and this gives u the circumference of the circle.Now from the circumference u can find the radius of the circle using the formula 2r. From the resulting radius u can easily find out the area of the circle using the formula

Answer 2

well is this a music question ??? XD
