Answer:
12.56 yd^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = pi (2)^2 (1)
V = pi (4)
Let pi = 3.14
V = 3.14 (4)
V =12.56
Answer:
36units^2
Step-by-step explanation:
we want to split this triangle into two different triangles, triangle 1 will have verticies (0,0) (3,8) and (3,0). Triangle 2 will have verticies (3,0) (3,8) and (9,0).
next we want to find the area of each of the triangles using the formula 1/2(base)(height)
Once you do this its just a matter of adding the two areas together.
1/2(3)(8)+1/2(6)(8)=12+24=36
Answer:
y = -2x - 1 ; slope = -2, y-intercept = (0, -1)
Step-by-step explanation:
to get the slope and y intercept, you need to put the equation into slope-intercept form: y = mx + b
the term mx is the slope of the line, and b is the y-intercept
to do this, you need to solve for y, so get y by itself by subtracting 8x from the left side
8x + 4y = -4
-8x. -8x
4y = -8x - 4
divide both sides by 4 to get y alone
4y/4 = y
-8x/4 = -2x
-4/4 = -1
y = -2x - 1 is the final equation
the slope of the line is -2 (also can be said as -2/1), and the line intercepts the y-axis at (0,-1)
