Answer:
224 in^3
Step-by-step explanation:
The foruma appropriate to the calculation of the cone's volume is ...
V = (1/3)Bh
where B represents the area of the base and h represents the height.
For your numbers, this is ...
V = (1/3)·(48 in^2)(14 in) = (16 in^2)(14 in) = 224 in^3
Find the slope, m = (change in y) / (change in x)
0-(-2)
Here, m = ------------- = 1/4
8 - 0
y-k = m(x-h) becomes y+2 = (1/4)(x), or y = (1/4)x - 2
Then the desired equation is y = (1/4)x - 2 (slope-intercept form)
Replace F in the equation with 113.
5/9(113-32)
5/9(81)
5 * 81 = 405
405 / 9 = 45 degrees Celcius
Your answer is the third one. WHen it comes to system of equations, this will cancel out 4a, therefore isolating the variable. That turns the equation into -2b=-5.
