Answer:

a) 301.6 cm^3.

b) 188.5 cm^2.

Both are correct to the nearest tenth.

Explanation:

Volume = 1/3 π r^2 h

= 1/3 * π * 6^2 * 8

= 301.59 cm^3

Area of the curved surface

= π L r where L = the slant height

= π * 10 * 6

= 188.49 cm^2.

Answer:

301.6, 188.5

Explanation:

to find the volume of the cone is πr
^(2) (h)/(3)

so π x 6
^(2) (8)/(3)

=301.59 or 301.6

now to find the curved surface area of the cone is πrl

so π x 6 x 10

=188.49 or 188.5
