Question

the volume of a right circular cylinder is 1100 cm*3 and the radius of its base is 5cm. Find its curved surface area ​

Answer 1

$\huge{\boxed{\mathtt{\red{ANSWER}}}}$

V = πr²h = 1100

22/7*5²*h = 1100

h = 1100*7/22*25 = 14cm

CSA = 2πrh = 2*22/7*5*14 = 440cm² (Ans)

(Mark as brainlist)

Answer 2

hey dude !!!!

curved surface area =2πrh

= 22×22/7×5×14

curved surface area= 440 cm square....

hope this helps you
