Answer:
yes
Step-by-step explanation:
Compare the areas of the 2 different pieces of paper.
For the circle, the area is A=pi * r^2, which works out to A = pi(5 inches)^2.
For the square, the area is A = s^2, where is the side length, which here is 11 inches.
Finish these calculations, and then compare your two areas. Which is the larger?
Answer:
#3 you are correct.
#4 you are correct.
Step-by-step explanation:
#3) Similar triangles have common ratio for all 3 sides.
AD=24 DB=27 EB=18
DB/AB = EB/CB
DB CB = EB AB
DB (CE+EB) = EB (AD+DB)
27(CE+18)=18(24+27)
CE=18(24+27)/27 - 18 = 16
#4) If the triangles are similar then their third sides are parallel
AD=15 DB=12 so AB=27
AE=10 EC=8 so AC=18
AC/EC = 18/10 = 9/4
AB/DB = 27/12 = 9/4
The triangles are similar, so BC || DE
Answer: 17
Explanation:
First: 30/-10 = -3
Second: (-20)/(-1) = 20
Third: -3 + 20 = 17
