Archy [21]
 so the ice rink diameter is 80 feet what mean that the radius of ice rink is 40 feet the walkway is 10 feet wide so 10+40=50 what mean that the radius and the walkway wide make 50 feet length together 
using this length area = pi*r^2 = 3,14*(50)^2 = 7850 feet squared
area of ice rink = 3,14*40^2 = 5024 feet squared 

area of the walkway = 7850-5024 = 2826 feet squared

A checking account rounds the amount of money deposited to the nearest hundredths place. After tax returns on April 15th, Yuan e
ludmilkaskok [199]

Answer:

\boxed{\text{\$336.35}}

Step-by-step explanation:

Yuan earned $336.3457.

You are asked to round this number to the nearest hundredth, that is, so there are only two digits after the decimal.

$336.34|57

A rule in rounding numbers is: if the first figure to be dropped is 5 with any nonzero digits following it, then the last figure kept should be rounded up (increased by 1).

The number becomes $336.35.

\boxed{\large \textbf{\$336.35}} \text{ was placed in Yuan's checking account}

Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in.
tankabanditka [31]

Answer:

The percentage error is 3.6 % .

Step-by-step explanation:

Formula

Error\ percentage = \frac{Error\times 100}{Exact\ value}

Error = \left |Approx - Exact \right |

As given

Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in.

Here

Approx value =  78.25 in

Exact value = 75.50 in

Error = \left |78.25 - 75.50\right |

Error = 2.75

Put in the formula

Error\ percentage = \frac{2.75\times 100}{75.50}

Error\ percentage = \frac{275}{75.50}

Error percentage = 3.6 %

Therefore the percentage error is 3.6 % .
