What is the circumference of a circle with a diameter of 4.1 cm ?

use 3.14 for pi.

12.874cm

Step-by-step explanation:

given

r=d/2=4.1cm/2=2.05cm

c=2πr

c=2×3.14×2.05cm

c=2×3.14×2.05cm

c=6.28×2.05cm

c=12.874cm

$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
