Answer:

Explanation:

I. Volume = 301.6 cm³ (to 1d.p)

II. CSA = 188.5 cm² (to 1d.p)

Explanation:

Given the following data;

Height, h = 8cm

Radius, r = 6cm

Curved length = 10cm

a. To find the volume of the cone

Where;

V is the volume of the cone.

r is the radius of the base of the cone.

h is the height of the cone.

Substituting into the equation, we have;

Volume = 301.6 cm³ (to 1d.p)

b. The curved surface area of the cone

Where;

CSA is the curved surface area of the cone.

r is the radius of the base of the cone.

l is the curved length of the cone.

Substituting into the equation, we have;

CSA = 188.5 cm² (to 1d.p)
