Find EM.<br> Can anyone help me with this?

Komok [63]

The little red dashes on the segments means they are congruent. EM = MG

Let's plug the expressions from the picture into our equation above.

7x = 8x - 6

Subtract 8x from both sides.

-x = -6

Divide both sides by -1

x = 6

EM = 7x = 7(6) = 42

Each base in this right prism-like figure is a quarter of a circle with a radius of 2m.

NISA [10]

Answer:

$volume = 10\pi m^3$

Step-by-step explanation:

Volume of a prism = Base Area x height

Base is a quarter of a circle.

$Area \ of \ circle = \pi r^2\\\\r = 2m\\\\Area \ of \ quarter \ of \ a \ circle = \frac{1}{4} \pi r^2 = \frac{1}{4}\pi \times 4 = \pi m^2$

Base Area = π square meters.

Therefore ,

$Volume = Base Area \times height = \pi \times 10 = 10\pi m^3$
