Question

the length of equator of the globe is 44cm.finds its suface area​

Answer 1

$\huge\rm\underline\red{☆ANSWER}$

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

Let radius r = x

Circumference of the globe =2πr

∴44=2×22/7×x

⇒x=44×7/44 = 7cm

Then Surface area of the globe = 4πr²

=4×22/7×(7)²=616cm²
