Question

If the area of the regular pentagon shown in the image is 60 cm and each of its sides measure 8 cm,
what is the area of the circle (in cm)?

Answer 1

Step-by-step explanation:

Area of Pentagon => 60

Side or Radius => 8cm { given}

Area of circle = πr^2

= 22/7 x ( 8 )^2

= 22/7 x 64

=>1408/7 {answer}

Answer 2

Area of Pentagon => 60cm²                            ( given)

Side or Radius => 8cm                                      ( given)

We know that area of circle = πr²

                                             = 22/7 x ( 8 )²          ( π = $\frac{22}{7}$ )

                                             = 22/7 x 64

                                             =1408/7 = 201.1 cm²

Hence the area of circle with pentagon is 201cm²

but the area of the circle with out pentagon will be = ( 201 - 60 ) cm²= 141cm²

Ans :- The area of circle with pentagon is 201cm²and  the area of the circle with out pentagon will be 141cm².
