Answer:
Cost, C = $28410.72
Step-by-step explanation:
We have, a concrete pillar has the shape of a cylinder.
Diameter of pillar is 8 m and ts height is 9 m
If concrete costs $87 per cubic meter, it is required to find the concrete cost for the pillar. For this lets find the area of cylindrical shape. So,
The cost of pillar at the rate of $87 per cubic meter will be :
Answer:
x=5
Step-by-step explanation:
The right angle opposite is the hypotenuse
The 30° is the opposite
SohCahToa
Soh = Sin because you got Opposite and Hypotenuse (because you're trying to find the side, you'd do the opposite of dividing, which is times)
10×sin(30)=5
I think is should be (5,0)
For this equation its the same as simplifying any other equation -Simplify both sides of the equation then isolate the variable- Easy then once you've do so the answer should be
<u>x = 
</u>
