The base is twice the height, or b = 2h. So, h = b/2. The area of a right triangle is (1/2)*b*h, and replacing h with b/2 you have (1/2)*b*(b/2), or (1/4)*b^2.So to write this it is<span> A(b) = (1/4)*b^2 for b >= 0</span>
Answer:
13.8
Step-by-step explanation:
1/2 base *height
1/2 6.9 *4 = 13.8
the scale has a persicion of 2 and it reads high.
The equation for the volume of a cylinder is pir^2h or 3.14*radius squared* height.
We can switch the equation around to find r^2=v/3.14*h
Now insert the known values.
R^2=1500/3.14*15
Solve
R^2=1500/47.1
R^2=31.8
R=5.6
Hope this helps!
Answer:
I am pretty sure it's 0.2
