r = 7cm (half of diameter)
Surface area = pi * r^2
= 22/7 * 7 * 7
= 22 * 7
= 154 cm^2
Hope this helps!

is it circle or sphere ????
616 ans
how
for sphere the formula for surface area is 4 pi r^2
so it must be surface area of sphere
ya
lets check 4 * 22/7 * 7 * 7 = 154 * 7 = 154 * 4 = 616
then why did u mention Circle in the question. circle and sphere are completely different -_-
thank
but now I cant edit my answer bcoz someone reported it
