Question

Cutting a circle into equal sections of a small central angle to find the area of a circle by using A=πr²?

Answer 1

This is one of our icse math project topics right?? Well our teacher explained it to us..first 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 2$\pi$r. From the resulting radius u can easily find out the area of the circle using the formula $\pi$$r^{2}$.

From the resulting radius u can easily find out the area of the circle using the formula \piπ r^{2}r
