What's the radius of a circle with an area of 64 square feet?
Nady [450]
Area = \pi r ^{2}
64 = \pi r ^{2}
\frac{64}{ \pi } =r^2
r= \frac{ \sqrt{64} }{ \sqrt{ \pi } } = \frac{8}{ \sqrt{ \pi } }

If you want the denominator rationalized, the answer is \frac{8 \sqrt{ \pi } }{ \pi }

tatuchka [14]

Answer:


Step-by-step explanation:

The book shelf arrived at the wholesale price = $ 147

So The Cost Price = $147

Markup = 60% = 0.60

So using the formula

Sale Price = Cost Price + Cost Price * Markup percentage

So

Sale Price = 147 + 147*(0.60)

Sale Price = $ 235.20
