1.	A piece of wire of length 108 cm is bent to form a semicircular arc bounded by its diameter. Find its radius and area enclosed. 2πr2+d=108 Area enclosed =πr22
Answer» A piece of wire of length 108 cm is bent to form a semicircular arc bounded by its diameter. Find its radius and area enclosed. $\frac{2 π r}{2} + d = 108$ Area enclosed $= \frac{π r^{2}}{2}$

Answer»

A piece of wire of length 108 cm is bent to form a semicircular arc bounded by its diameter. Find its radius and area enclosed.

$\frac{2 π r}{2} + d = 108$

Area enclosed $= \frac{π r^{2}}{2}$
