#### Solution

Given data is as follows:

Curved Surface Area = 267 m2

Volume = 924 m3

We have to find the height and diameter of this cylinder.

We know that,

Volume = pir^2h

pir^2h = 924

(pirh)r=924 ……(1)

Also, it is given that

Curved Surface Area = 267

That is,

2pirh=264

pirh = 264/2 ……(2)

Now let us replace the value of pirh in equation (1). We get,

(264/2) xx r =924

r=7

Therefore, diameter =  7 × 2

= 14 cm

Substitute the value of r in equation (2). We get,

22/7 xx 7 xx h = 264/2

h = 6

Therefore, the answer to this question is,

Diameter of the cylinder = 14 m

Height of the cylinder = 6 m

Is there an error in this question or solution?
