Math question, any is greatly appreciated! : )

Lateral Surface Area = π (5) (11.2) = 175.93 in²

Number of hats = 2500 ÷ 175.93 = 14

14 hats.

Hey user!

your answer is here..

ATQ,

we have to find out that how many cone birthday hats can we make out of 2500 in².

so, first of all we have to find the lateral surface area of one hat.

given :-

radius of the conical hat = 5 in

slant height ( length ) of the conical hat = 11.2 in

CSA ( curved/latera surface area ) of the conical hat = πrl

= 22/7 × 5 × 11.2

= 1232/7

= 176 in²

the lateral surface area of one hat is 176 in²

therefore no. of hats can be made from 2500 in² = 2500/176 = 14.20 ( approximately )

hence, 14 hats can be made.

cheers!!
