Robert is making five cone shaped party hats for sisters birthday party from cardboard each party has a radius of 7 inches and a slant height of 4 inches how much cardboard does Robert need front to the nearest 10th

Step-by-step explanation:

The lateral area of a cone is given by the formula

where

A is the lateral area

r is the radius of the cone

h' is the slant height of the cone

Here for the cone shaped party hats we have:

r = 7 in. is the radius of each cone

h' = 4 in. is the slant height

So the lateral area of each conic hat is

However, here we have five hats in total; therefore, the total lateral area of the 5 hats is

So, the amount of cardboard that Robert needs to make the 5 conic hats is .

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
