here you go ☆☆

17.

▪perimeter of triangle = 6.6×3 => 19.8
▪perimeter of triangle = circumference of circle
▪19.8 = 2pie×r

▪$19.8 \times \frac{1}{2} \times \frac{7}{22} = r$

▪r =3.15
▪d= r×2
▪ 6.3

18.

▪circumference of circle= perimeter of square

$2\pi \: r = 4a$

$2 \times \frac{22}{7} \times 56 = 4a$

$\frac{44 \times 8}{4} = a$

▪a = 88

hope it helps you........✌✌
