A = \pi {r}^{2}   \\  \\ r =  \frac{7.5}{2}  = 3.75

So

A = (3.14)({3.75}^{2} ) \\ A = (3.14)(14.0625) \\ A = 44.15625 \\ A =44.16

area =  \pi {r}^{2}  \\  r =  \frac{1}{2}  \times 7.5 = 3.75 \\ 3.14 \times 3.75  {}^{2}  \\ 3.75 {}^{2}  = 14.06 \\ 3.14 \times 14.06 = 44.1484 \: inches {}^{2}

hope that helped

Andres boards a Ferris wheel at the 3-o'clock position and rides the Ferris wheel for multiple revolutions. The Ferris wheel rot
Gelneren [198K]

Answer:

a) r(t) = 0.783t radians

b) h(t) = 30cos(0.783*t) feet

Step-by-step explanation:

The situation is depicted in the picture attached

<h3>(see picture) </h3>

Since the angular speed is constant, to find an expression for the angle r(t) in radians we just cross-multiply using the fact that 1 min = 60 seconds

4.7 radians __________ 60 seconds

r(t) radians ____________  t seconds

\large \displaystyle\frac{4.7}{r(t)}=\displaystyle\frac{60}{t}\Rightarrow r(t)=(4.7/60)t \Rightarrow\\\\\boxed{r(t)=0.783t\;rad}

The height h(t) after t seconds is given by

h(t) = 30cos(r(t)) ===>

h(t) = 30cos(0.783*t) feet
