area of circle =22/7×4=12.56
Answer:
Try 1
Step-by-step explanation:
The difference between 3 and 4 is one.
The density is 1g/cm³. To calculate density, the equation density=mass/volume is used. You already know the mass, 27g, but you need the volume. The equation for volume is length x width x height. Plug in your side measure 3, to get 3 x 3 x 3, which is 27cm³. Now, just divide the mass by the volume. 27g/27cm³= 1g/cm³
Answer:
x = 3
Step-by-step explanation:
Two triangles are similar
x/(x+3) = 4/8 cross multiply expressions
8x = 4x + 12
8x - 4x = 12
4x = 12 divide both sides by 4
x = 3
We use the tangent for this
tan 26 1 = opposite / adjacent = h / 205 where h = height of cliff
h = 205 tan 26 1 = 100 feet
