The surface area of a cone is found using the formula SA = Pir2 + Pirl. Describe what each part of the formula represents and how these parts are used to calculate the surface area.

hope it will help uh.....

 the first part is the area of the base:  πr²

You take the radius given, (or half of the diameter given) square that and multiply by the value of Pi, commonly 3.14 or 3.1416  

The second part is the area of the lateral surface. πrh That is the radius times π times the height of the cone.

Step-by-step explanation:

The formula as shown is confusing to me. It is better to show exponents with superscript if possible, or use the caret ^ [shift + 6] on a keyboard before the 2.

The second part is the area of the lateral surface. πrh That is the radius times π times the height of the cone. (using h instead of l seems less confusing as lower case L looks like 1 in some fonts) But people do use πrl  I realize.

Add the two surface areas together to get the total surface area of the cone.

each side has a different length.  

step-by-step explanation:

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 !
