Question

The area of base of right circular
cylinder as is 15400 cm^2 and its volume
is
'92400 cm3. Find its C-SA​

Answer 1

Answer:

volume=area× height

h= volume÷area = 92400÷15400= 6cm

base area = 15400

πr^2 = 15400

(22/7) r^2 = 15400

r^2 = 15400×7/22=100

r=√100 = 10cm

C. s. a. = 2πrh = 2 ×3.14× 10 × 6= 376.8cm^2
