C. Use the formula for area of a triangle 1/2(Base * Height). Using that we see that we have 1/2(a*b) + 1/2(c*c) + 1/2(a*b). Cleaning this up we get 1/2(2ab+c^2)

A wheel with a radius 10 inches covers a distance of 40pie inches in one second. What is the angular speed of this wheel?
andrezito [222]

Answer: B) 4\pi \text{ radians per sec }

Step-by-step explanation:

\text{Angular velocity} = \frac{\text{ linear velocity}}{\text{radius}}

Since, the wheel  covers a distance of 40\pi inches in one second.

Thus, its linear velocity = 40\pi\text{ per second}

Also, the radius of wheel = 10 inches,

Hence its angular velocity = \frac{40\pi}{10} = 4\pi\text{ radians per sec}

⇒ Option B is correct.
