Question

The circumference of a circular park is 176 m. Find the area of the park.

hint Hint:

try to find radius of the park

The correct answer is: 2464 cm2

It is given that Circumference of the circular park = 176 m
$rightwards double arrow$ 2 $straight pi$ r = 176
$rightwards double arrow$ 2 ( $22 over 7$ ) r = 176
$rightwards double arrow$ r = $fraction numerator 176 cross times 7 over denominator 2 cross times 22 end fraction$
$rightwards double arrow$ r = 28 m
Area of the park = $straight pi$ r²
= $22 over 7$ × 28²
= 2464 cm²
