Answer 1

Answer: OPTION C

Explanation:

The formula for calculate the surface area of a cone is shown below:

`SA=rl\pi+r^(2)\pi`

Where r is the radius, l is the slant height and SA is the surface area of the cone.

Substitute the values into the formula shown above. Therfore, the surface area of the cone is:

`SA=(7cm)(10cm)\pi+(7cm)^(2)\pi=119\pi`cm²
