Answer 2

Answer:

154 cm^2

Step-by-step explanation:

Circumference formula = 2$\pi$ r

Difference = Circumference - radius

37 = 2 × 22/7 ×r - r

37 = r (2 × 22/7 - 1)

37 = r (44/7 - 1)

37 = r (44 - 7 / 7)

37 = r (37/7)

37 × 7/37 = r

r = 7

Area = $\pi$ r²

= 22/7 ×7×7

= 22 ×7

= 154 cm²

Therefore area of the circle is 154 cm²
