the volume of a cylinder:
V=r%5E2%2Api%2Ah
and surface area of a cylinder:
A=2r%5E2%2Api%2B2%2Api%2Ar%2Ah
given:
h=+6m
d=4m... if diameter d=4m, then radius r=2m

V=r%5E2%2Api%2Ah....plug in given values
V=%282m%29%5E2%2A3.14%2A6m
V=4m%5E2%2A3.14%2A6m
highlight%28V=75.36m%5E3%29


A=2r%5E2%2Api%2B2%2Api%2Ar%2Ah...plug in given values
A=2%282m%29%5E2%2A3.14%2B2%2A3.14%2A2m%2A6m
A=2%2A4m%5E2%2A3.14%2B2%2A3.14%2A2m%2A6m
A=8m%5E2%2A3.14%2B75.36m%5E2
A=25.12m%5E2%2B75.36m%5E2
highlight%28A=100.48m%5E2%29
