Question

The length of Equator of the globe is 44cm . find its surface area​

Answer 1

Answer:

616cm^2

Step-by-step explanation:

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

Let radius r=x

Circumference = of the globe =2πr

∴44=2×227×x

⇒x=44×744=7cm

Then Surface area of the globe = 4πr2=4×227×7^2

=616cm^2

Answer 2

Answer:

the length of the equator means the circumference = $2\pi r$

$2\pi r$ = 44 cm

r = 44 × 7/22 × 2

r = 7 cm

TSA = $4\pi$r^2

= 4 × 22/7 × 7^2 = 616cm^2
