Answer:

Area of a circle=πr^2

12 inch pizza

π(6^2)≈113.04in^2

15 inch pizza

π(7.5^2)≈176.625in^2

Now we turn this into a fraction, and solve the problem:

113.04/10.99=176.625/x

113.04x=1941.10875 <-------Division property of equality

x=17.171875.

The cost of a 15 inch diameter pizza is $17.17

Hope this helped.

Mila [183]

The Area of the platform is 33m²

Step-by-step explanation:

As the question says, the height of vertex from the base (D from AB) is 7m whereas the height of left vertex from the base (E from AB) is 4m

Thus it means the height of the Δ DCE (DX)= 7-4 ⇒3m

Since the platform is five-sided, the figure can be broken down into constituting parts

  1. Parallelogram ║ABCE
  2. Δ DCE

Are of the figure= Area of ║ABCE+ area Δ DCE

Area of ║ABCE= breadth * height

= 6*4 ⇒24m ²

Area Δ DCE= ½*(base)(height)

Putting the value of base is 6m and height as 3m

Area Δ DCE= ½*6*3

=9m ²

Total area= 24+9= 33m ²
