Answer:

  • 3 feet is the start point

Step-by-step explanation:

<u>Function given:</u>

  • h(t) = −4.5t2 + 19.6t + 3

At t =0 we get h(0) = 3. This is called y-intercept

It is the start point indicating the disc was thrown at 3 feet height

A=3.14r^2 and d=12 A=?
zvonat [6]

\huge\boxed{113.04}

Diameter (d) is equal to twice the radius (r). So, find the radius by dividing \frac{12}{2}. The radius, or r, is 6.

Substitute in the value. A=3.14*6^2

Follow the order of operations and solve the exponent first. A=3.14*36

Multiply. A=\boxed{113.04}
