Find area of semicircle

Mumz [18]

Answer:

Step-by-step explanation:

So in this diagram the radius of semicircle = radius of a circle

So first we find the area of the circle (full circle)

Area of Circle =

$\pi \times r^{2}$

Keeping pi as 3.14 :

$3.14 \times 2 \times 2$

$3.14 \times 4 \\ = 12.56$

Area of Circle is 12.56

So Area of semicircle = 12.56/2

= 6.28

Use the position function s(t) = –16t2 + 800, which gives the height (in feet) of an object that has fallen for t seconds from a

Ostrovityanka [42]

Answer:

96 ft/s

Step-by-step explanation:

We can start by deriving the equation of the velocity, which is the derivative of the position equation:

$v(t) = \frac{ds}{dt} = (-16t^2)' + 800' = -32t$

After 3 seconds, the wrench would achieve a speed of

v(3) = -32t = -32*3 = -96 ft/s

So it's falling at the rate of 96 ft per second after 3 s
