A=π(10t)2=100πt2
B.
A=100×3.14×32=2826
Since each side is r times the side of ABC, then 30*r+40*r+60*r is the perimeter, which equals 130r (by separating it into r*(30+40+60) using the distributive property)
Answer:
slope = -10
Step-by-step explanation:
Answer: excellent geometry definition will classify, quantify, and not have a counterexample once parallel lines are defined, they can be used in the definition of a parallelogram.
