Hello,
Let's assume h the heigth of the parallelogram
h/6=sin 60°==>h=√3/2*6=3√3
Area=3√3 * 12=36√3
This is not a question...please rephrase.
The toppings would still cost 0.50 each (since it is just toppings)
The large pizza costs $18 if you do not have any toppings
The medium costs half of the large
18/2 = 9
The medium costs $9 without any toppings, so your new equation will be:
c = 0.50t + 9
hope this helps
Given =
Two similar pyramid have base area of 12.2 cm² and 16 cm².
surface area of the larger pyramid = 56 cm²
find out the surface area of the smaller pyramid
To proof =
Let us assume that the surface area of the smaller pyramid be x.
as surface area of the larger pyramid is 56 cm²
Two similar pyramid have base area of 12.2 cm² and 16 cm².
by using ratio and proportion
we have
ratio of the base area of the pyramids : ratio of the surface area of the pyramids

x = 12.2 ×56×
by solvingthe above terms
we get
x =42.7cm²
Hence the surface area of the smaller pyramid be 42.7cm²
Hence proved
