Answer:
1 is 2x45
2 is x348
3 is x78
4 is x89
Step-by-step explanation:
Answer: Scale factor is 2
Divide the x coordinates: 8/4 = 2
and do the same to the y coordinates: 6/3 = 2
we get 2 each time
The area is 35. Look at the sketch below for explanation!
V=hpr^2
V=10p(12/2)^2
V=360p cm^3 exact
V=1131 cm^3 (to the nearest tenth of a cubic centimeter)
