Answer:
813.4 cm² (nearest tenth)
Step-by-step explanation:
<u>Volume of a cylinder</u>
Given:
Use the Volume of a Cylinder formula and the given values to find the <u>radius of the cylinder</u>:
<u>Surface Area of a Cylinder</u>
Substitute the given value of h and the found value of r into the formula and solve for SA:
Therefore, the surface area of the cylinder is 813.4 cm² (nearest tenth)
For this problem, if we used b to represent your base angle measurement, you would add 8b+2b and set it equal to 180. This is because the measure of the vertex angle is 8 times the base angle measurement, so we had to multiply b by 8. We also had to add it to the other angle measures, so the other angle measures are represented as 2b since they are the same length. We then have to set this equal to 180 since that measures of a triangle must add up to 180. Then we combine like terms on our “b” side to get 10b=180. Then we divide both sides by 10 and we get b=18, which is the measure of our base angle.
Answer:
4x+8=-24 and
4x=-32
Step-by-step explanation:
2/3(6x+12)=-24
or,12x+24=-72
or,x=-72-24/12
•°•x=-8
4x+8=-24
or,x=-24-8/4
•°•x=-8
4x=-32
or,x=-32/4
•°•x=-8
(2 - 7 i) (-1 + 4 i).26 - (32 + 697 i)
Answer:
D.
Step-by-step explanation:
To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.
What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5
B.
left = -5 - 5 = -10
right = -(2/3)(4 + 4) = -16/3
So it's D. Let's verify:
D.
left = -5 + 5 = 0
right = -(2/3)(4 - 4) = 0
Checks out.
