The surface area of a cone is approximated by the polynomial 3.14r squared + 3.14rl where r is the radius and l is the slant height. find the approximate surface area of a cone when l=5cm and r=3cm

Step-by-step explanation:

answer: what equations are there

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
