Question

A circular garden has diameter equal to 56m. A
pavement is constructed around it. Find the area
of the pavement if its width is 7m.​

Answer 1

Step-by-step explanation:

According to the question,

Radius of garden=56/2

=28m

Area of garden= (pie)r^2

=(pie) 28^2

=2463m^2

Pavement=7m wide

So, 56+7+7=70

Radius=70/2=35m

Area=(pie)35^2

=3848.45m^2

So,

Area of pavement=a-a

=3848.45-2463

=1385.45m^2

Area of pavement=1385.45m^2
