Instead, break down the shape into rectangles. Next, calculate the area of both rectangles and add them together. The area of the first rectangle is 72 square centimeters and the area of the second rectangle is 50 square centimeters. Together there are 72 + 50 = 122 square centimeters.
That is how u find a irregular figure..hope this help u
Answer:
Ok so the first one is right and the second one is right for the first question
For the second Question your also right
Step-by-step explanation:
Question 3
12/7 is greater than 6/13 and it's asking what numbers would be incorrect meaning less than 6/13 (unmark 12/7)
1/10 is correct since 6/13 is greater than 3 / 65 (It's what you get when you multiple 1/10 with 6/13)
Unmark 4/3
Unmark 3
and 13/13 is just equal to 6/13 (leave unmarked)
Question 4
I don't know kiddo it's been a while
<u></u>
Answer: 26in
s=r*theta
r=s/theta
d=r*2
136ft=r*40pi
r=136/40pi=1.082ft
d=1.082*2=2.1645ft*(12in/1ft)=25.97in
Rounded to nearest in is 26in diameter
10 4 , so basically you cross multiply : 10x=20 .... 20 divided by 10 is 2 . x=2
___ = ___
5 x
I'm pretty sure its 1600m
