A circle with the radius of 3cm sits inside a circle with a radius of 7cm

natali 33 [55]

Answer:

Step-by-step explanation:

This will form a hollow circular part of a cylinder of outer radius 7cm and inner radius 3cm

Area of a circle is given by πr^2.

Then, the big circle of radius 7cm

Area= πr^2

Area=22/7×7×7

Area =154cm^2.

Area of the circle of radius 3cm

Area= πr^2

Area=22/7×3×3

Area =28.286cm^2.

Area of the shaded part becomes

Big area - small area

154-28.286

Area of shaded part = 125.7143cm^2

Then to the nearest hundredth

Area of shaded part =125.71cm^2
