Answer:

62.34

Step-by-step explanation:

Substitute n = 0 to n = 5 into the expression and sum the terms, that is

3 [ (\frac{3}{2}) ^{0}  + (\frac{3}{2}) ^{1} + (\frac{3}{2}) ^{2} + (\frac{3}{2}) ^{3} + (\frac{3}{2}) ^{4} + (\frac{3}{2}) ^{5} ]

= 3 [ 1 + \frac{3}{2} + \frac{9}{4} + \frac{27}{8} + \frac{81}{16} + \frac{243}{32} ]

= 3( \frac{665}{32} )

= 3 × 20.781

= 62.34 ( to the nearest hundredth )

The Solution:

GIven:

A=\pi r^2

Required:

Find\text{ }r\text{ when }A=81\pi in^2

Substitute:

\begin{gathered} \pi r^2=81\pi \\  \\ r^2=\frac{81\pi}{\pi}=81 \end{gathered}

Take the square root of both sides:
