Answer: area of rectangle
7x(7x2x3)
=294
area of 3 semicircles
7x2x3.14x0.5x3
=65.94
Answer
294-65.94
=228.06cm2
Step-by-step explanation:
The area of a circle is pi * r^2
The radius of the circle is 6
So the area of the full circle is pi*36
1/4 of the circle is cut off so we have to take a fourth off the area.
36pi * 3 / 4 = 27pi
Or 84.823 cm^2
For this, you use the Law of Distribution and multiply -1 by all terms in the parentheses. 7 • -1 = -7; -c • -1 = c. Then you combine them, but since c is a variable, -7 + c is the most simplified it can get. I hope this helped!
Answer:
50 times
Step-by-step explanation:
You are going to flip a coin 100 times. There are 2 sides. So, what you would do is divide 100 by two because there are two sides. There is a 50% chance that the coin will land on heads, and a 50% chance it will land on tails.
