(3 + ((1/9)*3) + (3/8) = 3 + 1/3 + 3/8 = 3 17/24

The formula of the triangle is 1/2 x b x h

The base of the triangle is 8 while the height is also 8

1/2 x 8 x 8 = 32 so B is the answer

The GCF is 45 and 9 is 9.

We can find the semicircle which has a Radius of one. The formula of finding the area of the 

half circle is 1/2\(\pi\)r^2. We know that the radius is one so we plug in that 1 for r. So our area of the semicircle is 1/2\(\pi \)

We can easily find the area of the rectangle which is 32cm.

Now we have our last figure which is the triangle. As shown, we know that the height of the triangle is 5cma and the base is 2 cm

1/2 x 2 x 5 = 5cm

Now we add all of the area 32cm + 5cm and 1.6cm ( which is half of pi) and the answer is 38.6cm^2

Hope this helps!

4 x 3 x 1.4  = 16.8 cm^3

Therefore the answer is D

This link has the answer.

Sorry but is there a diagram or a actual question?

I counted 24 ways total.

1):

We use the quadratic formula

 \(\frac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:1\cdot \left(-11\right)}}{2\cdot \:1}\)

We then simplify this quadratic formula into this\(\frac{-\left(-6\right)\pm \:4\sqrt{5}}{2\cdot \:1}\)

\(3+2\sqrt{5},\:x=3-2\sqrt{5}\)            The final answer is to the left. Hopefully this helps  

Didn't provide all the steps sorry.
