Answer:
1. To find the volume of a cylinder you'll need to use the formula V = pi(r)^2(h)
V = pi(4)^2(6)
V = 301.59
Rounded* = 301.6
2. A beach ball is a sphere, so we're going to use the formula 4/3pi(r)^3
4/3pi(18)^3
D = 24429.02
Rounded* = 24429.0
I cant read the last one completely, hope this helps.
Answer:
Step-by-step explanation:
Flipping a coin and rolling a number cube are both independent events. Independent events do not rely on the outcome of any previous events. This means that whatever you flip on the coin will have no effect on whatever you roll on the number cube and each flip of the coin or roll of the cube has the same probability as the flip or roll before.
The probability of getting tails on a coin toss is: 
The probability of getting a number less than 3 (so 1 or 2) on a number cube is: 
Since we are combining these events, we need to multiply the fractions together to get our overall probability:
*=

Step-by-step explanation:
First, find all the faces that you must find the areas of. In this case, you need to find the areas of two triangles and three rectangles.
In this triangular prism, the base is one triangle. If the area of the base is 7.75, we can assume that that holds true for both bases, and multiply 7.75 by 2 in order to find the area of both triangles.
Now find the area of each of the three rectangles by multiplying their individual heights and bases by each other. You should get 38, 47.5, and 38 as the areas of the rectangles.
Now add all the individual area's together. (They're bolded for clarity).
Answer:
X=-1
Y=1
Step-by-step explanation:
6x-12y
-18
) 6x + 4y
-
-2
Subtract the two equations
6x - 12y - (6x + 4y) = -18 - (-2)
Determine the sign
6x- 12y - 6x- 4y
=-18 + 2
Simplify
-12y
- Ay
=-18 + 2
Solve the equation
Substitute
6×+4
-2
Solve the equation
X=
