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
