To find the area, move each semicircle to fill up the square, you'll see there are three squares, each with an area of 4*4=16, so the total area is 3*16=48
Now the perimeter:
the perimeter of a circle is π times the diameter.
perimeter of each semicircle: (1/2)π*4=2π
there are altogether 6 arches and two straight sides, so the total is
2π*6+4*2=12π+8
the area is 48 square units, the perimeter is 12π+8 units.
Answer:..
Step-by-step explanation:
Answer:
1178.1
Step-by-step explanation:
pi*radius^2*height
Your answer would be 4c + 6 - 3c - 4
This is because when you simplify, you get 4c - 3c = c, and 6 - 4 = 2, so combining the two terms gives you c + 2.

To find the equation of a line, you need to find the slope and y-intercept by using the slope formula and point slope formula.
First, let's find the slope. 11 + 5/9 - 1 = 16/8 = 2. Therefore, the slope is 2.
Then, plug it into the point slope formula.
y + 5 = 2(x - 1).
Distribute: y + 5 = 2x - 2
Subtract 5 on both sides: y = 2x - 7.
Your final equation, that you need to plug into your answer, is y = 2x - 7.
