I knew there was a formula for this, but did not remember it and so had to look it up. The formula is:
A = pi*r*(r + sqrt(h^2+r^2) )
Here, A = 3.14(4 ft)(4 ft + sqrt(36 + 16) = 140.9 square feet.
When in doubt about a formula, look it up!
Answer:
5x^2 - 4x - 3 = 0
Step-by-step explanation:
For the equation
ax^2 + bx + c = 0
the roots are [-b +/- √(b^2 - 4ac)] / 2a
So comparing the terms to the values in the question:
a = 5
b = -4
c = -3
W= 79 brooooooooooooooooooo
there are 16 ounces in a pound so 16x7=112 +2= 114
