Answer:
Matt's Answer.
Step-by-step explanation:
Note that in the equation, you need a radius (r). However, a <em>diameter is given, which is 15 centimeters</em>. This means that, to solve this equation, you must first divide 15 by 2, to be able to continue to solve. In Matt's case, he failed to do that.

The area of a regular hexagon is A=(3√3/2)a², a is the side length.
so A=(3√3/2)*5.2²=70.25
C is the correct answer
I believe it’s A because that one makes sense the most
Answer: Multiply or Divide
Step-by-step explanation: You can multiply or divide by the cube of the scale factor. To decide if you should multiply or divide, you should consider the value of the scale factor and if you are going from a larger to a smaller figure, or a smaller to a larger.
We will first calculate the total cost in pounds then convert to dollars.
1- Equipment for three offices. The cost is 100 pounds per equipment.
Total cost of equipment = 3*100 = 300 pounds ..........> I
2- One switchboard. The cost is 333 pounds.
Total cost of switchboard = 333 pounds ...............> II
3- Total cost excluding taxes can be calculated by adding I and II as follows:
Cost excluding taxes = 300 + 333 = 633 pounds
4- Tax is 10% of the cost.
Tax amount = 0.1 * 633 = 63.3 pounds
5- Total cost including taxes = 633 + 63.3 = 696.3 pounds
6- Convert the cost to dollars.
We know that 1 pound is equivalent to 1.5$. To know the equivalence of 696.3 pounds, just do cross multiplication as follows:
Cost in dollars = (696.3*1.5) / 1 = 1044.45$
