Here are the calculations for the right circular cylinder:

Given:
Diameter, d=6 cmd = 6 \text{ cm}
Altitude (height), h=8 cmh = 8 \text{ cm}

  1. Calculate the radius.

    The radius is half of the diameter.

    r=d2=6 cm2=3 cmr = \frac{d}{2} = \frac{6 \text{ cm}}{2} = 3 \text{ cm}
  2. Calculate the Lateral Surface Area (LSA).

    The formula for the lateral surface area of a cylinder is LSA=2πrhLSA = 2 \pi r h.

    LSA=2π(3 cm)(8 cm)LSA = 2 \pi (3 \text{ cm})(8 \text{ cm}) LSA=48π cm2LSA = 48 \pi \text{ cm}^2

    The lateral surface area is 48π cm2\boxed{48 \pi \text{ cm}^2}.

  3. Calculate the Total Surface Area (TSA).

    The formula for the total surface area of a cylinder is TSA=2πr(h+r)TSA = 2 \pi r (h + r).

    TSA=2π(3 cm)(8 cm+3 cm)TSA = 2 \pi (3 \text{ cm})(8 \text{ cm} + 3 \text{ cm}) TSA=6π cm(11 cm)TSA = 6 \pi \text{ cm}(11 \text{ cm}) TSA=66π cm2TSA = 66 \pi \text{ cm}^2

    The total surface area is 66π cm2\boxed{66 \pi \text{ cm}^2}.

  4. Calculate the Volume (V).

    The formula for the volume of a cylinder is V=πr2hV = \pi r^2 h.

    V=π(3 cm)2(8 cm)V = \pi (3 \text{ cm})^2 (8 \text{ cm}) V=π(9 cm2)(8 cm)V = \pi (9 \text{ cm}^2)(8 \text{ cm}) V=72π cm3V = 72 \pi \text{ cm}^3

    The volume is 72π cm3\boxed{72 \pi \text{ cm}^3}.
