Question

8. What is the lateral area of the cone?​

Answer 1

`190.07 \: {yd}^(2)`

Option D is the correct option.

Explanation:

Diameter (d) = 10 yd

Radius(r) = 10/2 = 5 yd

Slant height (l)= 12.1 yd

We know,

Lateral surface area of cone:

`\pi \: r \: l`

`= 3.14 * 5 * 12.1`

`= 189.97 \: {yd}^(2)`

which is nearly 190.07 square yards.

Hope this helps...

Good luck on your assignment..

Answer 2

`190.07 {yd}^(2)`

Explanation:

`lateral \: \: area \\ = \pi \: rl \\ = 3.14 * 5 * 12.1 \\ = 189.97`

189.97 square yards which is nearly 190.07 square yards
