Radius = 3 units
Using pi as 3.132
Area of circle = \pi  r^{2} = 3.142 x 3 x 3 = 28.278 square units ≈ 28.28 square units

OR if you use the calculator and press pi x 3 x 3 = 28.27square units

Calculate the time required for an object to increase velocity from 25 ft/s to 125 ft/s. Use the formula V = V0 + 32t, where V0
Alborosie
Using the equation of motion:
V=V_0+32t

Plug in the final velocity:V=125
and the initial velocity:V_0=25

Then you would get:
125=25+32t\\
125-25=32t\\
100=32t\\
t= \frac{25}{8} \\
t=3.125
