The formula of an area of a circle:

A_O=\pi r^2

We have

r = 1.8 m

π ≈ 3.14

Substitute:

A_O=\pi\cdot1.8^2=3.24\pi\ m^2\approx3.24\cdot3.14=10.1736\ m^2\approx10.17\ m^2

In ABC, what is the value of x?<br><br> Pls hurry im on a time limit here
kiruha [24]

Answer:

70

Step-by-step explanation:

By exterior angle theorem:

(2x + 12) \degree = 112 \degree + 180 \degree - 2x \degree \\  \\ (2x + 12) \degree = 292 \degree - 2x \degree \\  \\ (2x + 12) \degree  + 2x \degree = 292 \degree \\  \\ (2x + 12 + 2x) \degree = 292 \degree \\  \\ (4x + 12) \degree = 292 \degree \\  \\ 4x + 12  = 292  \\  \\ 4x = 292 - 12 \\  \\ 4x = 280 \\  \\ x =  \frac{280}{4}  \\  \\ x = 70
