Given: Lateral area = 68

AO = 3.4

Find: m∠SAB

Step-by-step explanation:

Surface Area of a Cone

The surface area of a cone is given by

Where r is the radius and hs is the slant height measured from the top to any point at the circumference of the base. The cone shown in the figure has a radius r=3.4 and a surface area of 68.

Solving for hs

But hs is equal to AS. The triangle SAO has an angle of 90° at the point O. The required angle  m∠SAB can be found by applying the cosine ratio:

Thus

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
