A cylindrical juice glass is 8 centimeters tall and has a radius of 3 centimeters. If the glass is full, which of the following is closest to the volume of the filled portion? A) 28 cm C) 170 cm B) 226 cm D) 98 cm PLEASE HELP!
Answer:
226
Step-by-step explanation:
You first have to find the volume of the cylinder, which you would do 3 squared, which is 9, times 8, which is 72, and then times pi, which gives you 226.1946711. Since they want the closest volume to that number, it would just be 226. If you are confused on the equation, the equation for the volume of a cylinder looks like this: [tex]V=\pi(r^{2})(h) \\[/tex], where r is the radius and h is the height.

help me ya'll so i can go to bed! (slopes) (brainliest)
Answer:
i dont know
what you wanna know
Step-by-step explanation:
Identify the coordinates (x₁,y₁) and (x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).
Input the values into the formula. ...
Subtract the values in parentheses to get 2/ (-5).
Simplify the fraction to get the slope of -2/5.

Find the value of x and y. pls help !!
Write the equation of the line graphed below
Answer:
y = 5/8x + 12
Step-by-step explanation:
Slope = change in y/change in x
slope = 5/8
Using y = mx + b find b.
y = 5/8x + b
-2 = 5/8(-4) + b
b = 1/2
y = 5/8x + 12
good luck, i hope this helps :)

Select all the equations that are equivalent. 52 = 8n + 4 4(2n + 1) = 52 4 = 52 – 8n 4n = 48 n = 6
Answer:
52 = 8n + 4
4(2n + 1) = 52
4 = 52 – 8n
n = 6
Step-by-step explanation:
52 = 8n + 4
52 - 4 = 8n
48 = 8n
n = 48/8
n = 6
4(2n + 1) = 52
8n + 4 = 52
8n = 52 - 4
8n = 48
n = 48/8
n = 6
4 = 52 – 8n
4 - 52 = -8n
-48 = -8n
n = -48/-8
n = 6
4n = 48
n = 48/4
n =12
n = 6
52 = 8n + 4 is equivalent to 4(2n + 1) = 52 is equivalent to 4 = 52 – 8n is equivalent to n = 6

Gabby has $1,506 in a savings account that pays 2.5% simple interest. How much interest will she earn in 3 years?
Answer:
$112.95
Step-by-step explanation:
Use the simple interest formula, I = prt
Plug in the initial amount, interest rate, and number of years
I = prt
I = (1506)(0.025)(3)
I = 112.95
So, the interest created in 3 years is $112.95

Answer:
so the smallest side would be associated with the smallest angle, and the angle is directly across from the side. To write from smallest to largest angle would be:
angle V because it's across from the smallest side
angle S because it's across the second smallest side
angle T because it's across the largest side
Tremaine scored 54 three-point goals, 84 two-point field goals, and 106 free throws in 23 games. How many points did he score on average per game
Answer: 18.96
Step-by-step explanation:
From the question, Tremaine scored 54 three-point goals, 84 two-point field goals, and 106 free throws. The total point scored will be:
=(54 × 3) + (84 × 2) + (106 × 1)
= 162 + 168 + 106
= 436 points
The number of points scored on average per game will then be:
= 436 / 23
= 18.96 points per game

Answer:
Step-by-step explanation:
Volume of the cylinder
Givens
h = 30-10 = 20
d = 20
r = d/2 = 20/2 = 10
Formula
V = pi r^2 h
Solution
V = 3.14 * 10^2 * 20
V = 6280
Volume of the cone
Givens
h = 10
d = 20
r = d/2 = 20 / 2 = 10
Formula
V = 1/3 pi r^2 h
V = 1/3 * 3.14 * 10^2 * 10
V = 1046
Total Volume
V_cone + V cylinder
V = 1046 + 6280
V = 7326.7
