Question

please answer this question ​

Answer 1

Answer:

(4).

Step-by-step explanation:

height of cylinder = 28cm

circumference of curved surface will be 88 cm

2(pi)r = 88

(pi)r = 44

r = 14cm

volume of cylinder = (pi)r^2 ×h

= (pi) 14^2 ×28

= (pi) 5488cm^3

= 5488(pi) cm^3

Answer 2

Answer:

vol of cylinder = 17248 cubic cm

Step-by-step explanation:

area of paper = l×b = 88×28 =2464 sqcm

CSA of Cylinder= 2464

2πrh= 2464

2× 22/7 × r ×28 =2464

44×28/7 ×r = 2464

r = 2464×7/44×28 = 14cm

vol = π r^2h = π×14×14×28

vol of cylinder = 5488π cubic cm
