Question

circular base of a cone is 616 CM square and its height is 48 cm find its whole surface area

Answer 1

its the answer. please check it and like it my dear friend

Answer 2

acc to que. π r^2 = 616
(22×r^2)/7=616
r^2 = 28×7
r = 7×2= 14
H=48 cm
so L= (14^2+48^2)^1/2 = (196+2304)^1/2 = (2500)^1/2 = 50
A= π r (r+L) = 22/7 × 14× (14+50) = 44×64= 2816cm^2
