Answer:
About 10.05
Step-by-step explanation:
The change in x is 1, so the bottom line is a length of 1. The change in y is 10, so the right line is 10. Since a^2+b^2=c^2, 1^2+10^2=101, and the square root of 101 is about 10.05.
11. 28*21 = 588 cubic feet
12. 16*9/3 = 48 pi ~150.72 ~ 151 cubic inches
13. 9*9*14/3 = 378 cubic yards
