Question

the length of equator of the globe is 44 cm. Find it's surface area​ ​

Answer 1

Step-by-step explanation:

length of equator = circumference of globe/sphere

=> 2πr = 44

or r = 7

so surface area of globe/sphere = 4πr^2

= 4*(22/7)*7*7

= 616 cm^2

Answer 2

d=44

so r=22cm

surface area=

$4\pi {r}^{2}$

$4 \times \frac{22}{7} \times {22}^{2} \\ \frac{88 \times 484}{7} \\ 42529 \div 7 \\ = 6084.57 {cm}^{2}$
