3. The length of equator of the globe is 44 cm. Find its surface area.

Answer»

Length of the equator of the globe or circumference of a globe = 44 cm

r = ?

Circumference = of the globe = 2πr

44 = 2*22/7*rr = (44*7)/44r = 7 cm

Now,Surface area of the globe = 4πr²= 4*22/7*7*7

Surface area = 616 cm²
