Didn’t he lateral area of the cone in terms of pi.

 sq. in.

Step-by-step explanation:

The lateral area of cone is given by the formula  

Where,

r is the radius, and

l is the slant height

Plugging all these values into the formula, we get:

Lateral Area =

third option

Step-by-step explanation:

To solve the problem you must apply the following formula for calculate the lateral area of a cone:

Where r is the radius and s is the slant height.

As you can see in the figure:

Substitute values. Therefore, the result is:

 in²

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
