Question

find the total surface ares of a cylinder whose base area is 38.5cmsquare and height is 9cm steps required

Answer 1

Answer:

275 sq cm

Step-by-step explanation:

base area= 38.5 sq cm- ba

ba= 22/7 * r * r

r^2= 12.25

r=3.5

surface area = (22/7 * r^2 * 2) + (2* 22/7* r * h)

= 77 + 198= 275 sq cm
