Answer:

Area=190.091 cm^2

Step-by-step explanation:

Area = 1/2(Pi x r^2)    one-half because it's a semi-circle

Area=1/2(3.14 x 11^2)

11^2=121 so, Area=1/2(3.14 x 121)

Area=1/2(379.94)

Area=189.97 cm^2

adjustment:

Area=1/2(3.142 x 11^2)

Area=1/2(3.142 x 121)

Area=1/2(380.182)

Area=190.091

Answer:

Step-by-step explanation:

The area of a rec tangle is A x W

but first you have to find the area of the triangle wich is going to be 127.5.

Then you have to multiply 127.5 times 15.

And that will give you 1,912.5.

I think this is correct, but im not sure.

How many solutions are there to the equation below?
Vikentia [17]

Answer:

5x + 48 + 7x = 12(x + 4) \\ 5x + 48 + 7x = 12x + 48 \\ (5x + 7x) + 48 = 12x + 48 \\ 12x + 48 = 12x + 48 \\ 12x - 12x = 48 - 48 \\ 0 = 0
