• The total surface area of a cylinder is given by:


SA=2πr\left(r+h\right)

where r = 1.75 cm

h = 3 cm

Hence:


SA=2*\pi*1.75*(1.75+3)=57.7\text{ }cm^2

• The volume of a cylinder is given by:


V=πr^2h

Hence:


V=\pi*(1.75)^2*3=28.9\text{ }cm^3

ANSWER

surface area = 57.7 cm²

volume = 28.9 cm³
