A semicircular flower bed has a diameter of 3 metres.
Kaylis [27]

Answer:

3.5 m^2

Step-by-step explanation:

If the shape is half of a circle, you will be using this formula: A = \frac{1}{2} π r^2

Your radius is half of the diameter. r = d/2 = 3/2 = 1.5

Substitute r = 1.5 into the formula.

A = \frac{1}{2} π 1.5^2

A = \frac{1}{2} (3.14) 1.5^2

Use your calculator to find the answer and round your answer.

3.5

svp [43]

Answer:

The Total amount of of 33 boxes of chocolates including taxes is $838.358

Step-by-step explanation:

Given as :

The sales tax rate for city = 4.306%

The sales tax rate for the state = 44%

Total number of boxes = 33

The price of each chocolates = $17.13

So , The price of 33 boxes of chocolates = $17.13 × 33

I.e The price of 33 boxes of chocolates = $565.29

Now total tax including state and city =  4.306% + 44% = 48.306 %

So, The tax amount paid for 33 boxes of chocolates = 48.306 % of $565.29

∴    The tax amount paid for 33 boxes of chocolates = 48.306 % × $565.29

                                                                       = 0.48306× $565.29

                                                                       = $273.068

∴ The Total amount of of 33 boxes of chocolates including taxes = $565.29 +  $273.068 = $838.358

Hence The Total amount of of 33 boxes of chocolates including taxes is $838.358 . Answer
