Hope this helps :)
If only it was in english i could of read it and gave you the answer
Answer:
3.14 square units
Step-by-step explanation:
Circumference of a circle = 2πr
2πr = 6.28
r = 6.28/2π
r = 3.142/π
Area of a circle = πr^2
slot in the value of r
Area of the circle = π( 3.142/π)^2
" = π(9.87/ π^2)
" = 9.87/π
π = 3.14
Area of a circle = 9.867/ (3.14)
" = 3.14 square units
I do not understand ???????????????????
Okay, here we have this:
Considering the provided information, we are going to calculate the requested value, so we obtain the following rule of three:
Solving for x:
Finally we obtain that 87.5mL of water should be used for 250g of plaster.
