Answer:

Area of stage is:

1133.54 square feet

Step-by-step explanation:

Area of circle is given by:

A= πr²

where r is the radius of the circle.

Here we are given a stage in the shape of a circle with radius r=19 feet

Area of stage= π×19²

                     = 3.14×19×19

                     = 1133.54 feet²

Hence, Area of stage is:

1133.54 square feet

Express the complex number in trigonometric form. -4
salantis [7]
Ok this is a negative number. 
All negative numbers have argument \pi
Obviously, the module of this number is \vert-4\vert=4
The general trigonometric form of a complex number is:
z=\vert z\vert(cos\theta+i\sin\theta)
We deduce the trigonometric for of -4:
-4=4(cos\pi+i\sin\pi)

OGD Electronics Store buys digital cameras from the manufacturer at $193.55. It then marks them
inessss [21]

Answer : The selling price when you visit the store will be, $435.49

Step-by-step explanation :

Given:

Cost price = $193.55

Profit percent = 125 %

First we have to calculate the total profit.

Total profit = \$ 193.55\times 125\%

Total profit = \$ 193.55\times \frac{125}{100}

Total profit = $241.94

Now we have to calculate the selling price.

Selling price = Cost price + Total profit

Selling price = $193.55 + $241.94

Selling price = $435.49

Therefore, the selling price when you visit the store will be, $435.49
