Ex 6.1, 7 (i) Find the total perimeter of all the petals in each of the given flowers. We can separate this into 4 semicircles of Diameter 14 cm Now, Perimeter of shape = 4 Γ Circumference of semicircle with Diameter 14 cm = 4 Γ Circumference of semicircle with Radius 7 cm = π Γ π/π Γ π Γ π Γ π = 4 Γ π Γ 7 = ππ Γ π = 28 Γ22/7 = 4 Γ 22 = 88 cm
