Question

find the volume of the cone and the curved surface area of the cone

Answer 1

Answer:

301.6, 188.5

Step-by-step explanation:

to find the volume of the cone is πr$^{2} \frac{h}{3}$

so π x 6$^{2} \frac{8}{3}$

=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

Answer 2

Answer:

a) 301.6 cm^3.

b)  188.5 cm^2.

Both are correct to the nearest tenth.

Step-by-step 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.
