Question

please tell me if this is correct with explanation

Answer 1

14 ×14=196
$\pi \times {14}^{2}$
$22 \div 7 \times 14 \times 14$

Answer 2

area of 2 semicircles = 2 × 1/2 × π × 14 × 14
= 22×2×14 =22×28
area os square = 28 × 28
area of unshaded portion = 28(28 - 22)
= 28×6=168 cm^2
So your answer is correct
