A chef cuts a watermelon along its horizontal diameter once and then along its vertical diameter twice at right angle to each other. A slice is removed (other pieces remains intact). What will be the total surface area of the remaining portion?
Choose the correct choice from the following: A) 4*pi*r^2 B) 4*pi*r^3 C) 4*pi*r^4 D) 4*pi*r^5 E) 4*pi*r^6
surface area of sphare is (4*pi*r^2)   if 1/4th parth is removed (4*pi*r^2)-(pi*r^2)= 3*pi*r^2   and the cut surface is (1/2*pi*4^2)*2   so total surface area is 4*pi*r^2   4*pi*r^2NSWER:4*pi*r^2
