Here are the calculations for the right circular cylinder:

Given:
Radius, r=4 cmr = 4 \text{ cm}
Altitude (height), h=10 cmh = 10 \text{ cm}

  1. 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(4 cm)(10 cm)LSA = 2 \pi (4 \text{ cm})(10 \text{ cm}) LSA=80π cm2LSA = 80 \pi \text{ cm}^2

    The lateral surface area is 80π cm2\boxed{80 \pi \text{ cm}^2}.

  2. 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(4 cm)(10 cm+4 cm)TSA = 2 \pi (4 \text{ cm})(10 \text{ cm} + 4 \text{ cm}) TSA=8π cm(14 cm)TSA = 8 \pi \text{ cm}(14 \text{ cm}) TSA=112π cm2TSA = 112 \pi \text{ cm}^2

    The total surface area is 112π cm2\boxed{112 \pi \text{ cm}^2}.

  3. Calculate the Volume (V).

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

    V=π(4 cm)2(10 cm)V = \pi (4 \text{ cm})^2 (10 \text{ cm}) V=π(16 cm2)(10 cm)V = \pi (16 \text{ cm}^2)(10 \text{ cm}) V=160π cm3V = 160 \pi \text{ cm}^3

    The volume is 160π cm3\boxed{160 \pi \text{ cm}^3}.
