Answer:

Step-by-step explanation:

radius of a coin is 12 mm

Diameter of the coin is twice the radius  = 2 x 12mm = 24mm

The circumference of the coin= 2πr = 2 x3.14 x 12 = 75.36m

Area of coin = πr²= 3.14 x 12 x12 = 452.16mm²

alexgriva [62]
First of 3/7 of a week is 3 days because there are 7 days in a week e out of seven so you get it?

1. The question is asking you how much barrels of raisins is used in three days but first you need to find out how much they use in 1 day (this is how I would do it) so turn all the fractions into a decimal

4/9 = 0.4444...
6/5= 1.20
3/7= 0.43

So now you got your decimals

2. Multiply 0.4444 by 1.20 now you got how much you get a day for cosmos bakery which is 0.53

3. Now go back to the 3/7 of a week which is 3 days and now you need to multiply 0.53 by 3 and you will get your answer

ANSWER!

1.59 a day for cosmos bakery
