Answer:
30.3m^2
Step-by-step explanation:
I started off by finding the area of the semi circle. The formula πr^2 divided by 2. The radius of the circle is 2 because it is half of the diameter which is 4. So π(2)^2 divided by 2 is 6.3.
Next I broke apart the the shape into a rectangle and a triangle for simplicity sake. So doing this I had to know where to cut and if you look at the top of the figure it shows 2m for the length at the top. So I put a vertical line there. Thus changing the 10m on the bottom to a 8m section and a 2m section. So the rectangle's area will be the length times the height which is 2x4=8.
The triangle's area can be found with the equation BH/2 and we the 8 base we found and a height of 4 it is 8x4/2. Which ends up as 16.
Finally you add up all three area's that you found 8+16+6.3=30.3
Answer:
Step-by-step explanation:
x = 1
Step 1: Simplify both sides of the equation.
20x−−2x−16=6
20x+2x+−16=6
(20x+2x)+(−16)=6(Combine Like Terms)
22x+−16=6
22x−16=6
Step 2: Add 16 to both sides.
22x−16+16=6+16
22x=22
Step 3: Divide both sides by 22.
22x
22
=
22
22
The discriminant is the square root of -7.
Answer: 9k+9f+9h

I saw the image that should have been included in this problem.
It was a rectangular prism. It can also be identified as a right prism because its bases are aligned one directly above the other and its lateral faces are rectangular.
The image has the following measurements:
length = 7 inches
width = 5 inches
height = 4 inches
volume = length * width * height
v = 7 in * 5 in * 4 in
v = 140 in³ Choice B i believe.
