Volume (V) of a cylinder = B x h ; where B is the area of the base and h is heighth
65 π = B x 5
13 π = B <em>divided both sides by 5</em>
Answer: 13π cm²
Answer:
The number is 1.
Step-by-step explanation:
If you simplify the equation, it goes to 4x+5=3x+6. Subtract 5 from both sides and you get 4x= 3x+1. The only number that satisfies that equation is 1.
When it says x and y are directly related it means that x is multiplied by something to get y. To solve you divide y by x which is 840 divided by 6. Which is 140 then you multiply and solve so the y value for 5 is 700. The x value for 420 is 3 and the y value for 4 is 560.
We know that 
and this is the only point when sin and cos are equal lengths. Because both 
Now if the sin of 30° is a half that would mean that cos of 60° is also a half.
Hope this helps.
