Ah ok The property is
"The Addition Property of Equality"
Answer:
The third answer
Step-by-step explanation:
(side note: You probably need to use a calculator that can calculate pi)
The formula to find the area of a circle is pi r squared.
In this case, pi times r squared is 19.63495....... continued
This is probably going to be rounded
so... 19.63
For all of the circles, this is multiplied by 4.
This is 78.52
The area of the square is 100 cm since 10 times 10 is 100
You take 100 cm and then subtract it by 78.54
Voila! now you have 21.46
Simplify the expression and you get: 8.6
Hope this helps!
2 km... Since 1.8 is 2(.9), you do the same for the base of the smaller triangle (just multiply by two)
