Question

1. Find the volume, curved surface area and total surface area of each of
these
dimensions are:

(1) radius of the base = 7 cm and height = 50 cm
(2) radius of the base = 5.6 m and height = 1.25 m
(3) radius of the base = 14 dm and height = 15 m​

Answer 1

Answer:

Volume of a cylinder =

Lateral surface

Total surface area

(i) Base radius = 7 cm; height = 50 cm

Now, we have the following:

Volume

Lateral surface area

Total surface area

(ii) Base radius = 5.6 m; height = 1.25 m

Now, we have the following:

Volume

Lateral surface area

Total surface area

(iii) Base radius = 14 dm = 1.4 m, height = 15 m

Now, we have the following:

Volume

Lateral surface area

Total surface area
