What is the area of d=8 and r=4
Alex

So, for the semi circle, we need to find the area of a circle then divide it by 2.

pi times r squared

\pi 16 is the area of a circle with the radius of 4

(I'm going to use 3.14 as pi)

So 3.14 times 16 is 50.24

Divide that by 2 and we get 25.12

For the rectangle at the bottom. We know that the radius is four, so we can cut off 4ft from the height, leaving us with 8.

8 times 8 is 64.

To find the area of the whole figure, we add 64 and 25.12 together, getting 89.12

So the area is 89.12 feet squared.


Any questions?

the sum of the speeds of two trains is 716.7 miles per hour if the speed of the first train is 5.3 miles per hour faster than a
Nimfa-mama [501]
The best way to solve this is to make an algebraic expression to represent the situation~
If x is the speed of the first train and y is the speed of the second we can make 716.7 = x + y
the first train is 5.3 mph faster so x = y + 5.3
Now we can replace x with our new value to get 716.7 = y + (y+5.3)
Simplify and we get 716.7 = 2y + 5.3
Now all we got to do is simplify this equation, 716.7 - 5.3 = 711.4. Divide by 2 to get 355.7 for the speed of the second train. Since the first train is 5.3 mph faster, we add that to the second trains value and get our answer. The first train is going at 361.7, the second at 355.7

In the figure below, triangle ABC is similar to triangle PQR:
miskamm [114]

Answer:

The length of PQ is 24

Step-by-step explanation:

If you flip triangle PQR upside down the you can see which side corresponds to which. BC corresponds to QR and AB with PQ, the scalar is 6 because of BC (2) times 6 = QR (12). So you just have to do 4 times 6 which is 24.
