Answer:
44.1 mm^2
Step-by-step explanation:
The formula for a trapezoid is 1/2(b1 + b2)h
A= 1/2(12.5 + 8.5) 4.2
= 1/2x21x4.2
=44.1
Answer:
11.25
Step-by-step explanation:
15*(1-25%)=11.25
All you have to do is multiply it then you get the answer
We Know, Circumference of Circle = 2πr
Here, r = 18
Substitute it in to the expression,
C = 2π(18) = 36π
So, your final answer is 36π
Hope this helps!
Only multiplication and division don't change the ratio that made the order pairs in the bigger picture the triangle. Only one is not congruent. I'm about 90% sure I got it correct.
