Explanation:

question 6 = Volume ; 2389.2cm^3 or 2389 cm^3 to 4sf.

Step-by-step explanation:

question 6 =

We have 13 Diameter. Which is 6.5 radius

D = 13

R = 6.5

H = 18

Surface area a of cylinder pi x 6.5^2 =  132.73229

or 42.25pi

Then we just multiply by the height to get the volume.

42.25x 18 = 760.18 pi

or 132.73229 x 18 =2389.18122

Volume = 2389.2cm^3 or 2389 cm^3 to 4sf.
