Answer:
V = 65.19
Step-by-step explanation:
Remark
You need r. You can get it from the circumference of the circular base.
Once you have that, the formula is Area = 1/3 pi r^2 j
Givens
C = 20.236
h = 6 feet
Formulas
C = 2 pi r
Volume = 1/3 pi r^2 h
Solution
Find r from C = 2 pi r
20.236 = 2 * 3.14 * r Combine the right
20.236 = 6.28 * r Divide by 6.28
20.236/6.28 = 6.28 * r / 6.28
3.222 = r
Now that you have r, you can solve for the volume
V = (1/3) pi 3.222^2 * 6 Square r
V = 1/3 * pi * 10.381 * 6 Now multiply through by all, but pi
V = 20.762 pi
V = 65.194
Answer:
Length of the minor arc AB = 5.27777777778 cm
Step-by-step explanation:
Here you would require a simple proportionality.
The ratio of the degree of the minor arc (95 degrees) over the total, 360 degrees of every circle, comparative to the length of the minor over the circumference (20 cm).
Here we can propose that the length of the minor can be equal to x.
Now let's substitute the known values:
95 / 360 = x / 20
Now cross multiply:
360 * x = 95 * 20 ⇒
360x = 1900 ⇒
x = 5.27777777778 ⇒
length of the minor arc AB = 5.27777777778 cm
2 supplementary angles when added together need to equal 180 degrees.
Add:
3x-23 + 2x-12 = 180
Simplify:
5x -35 = 180
Add 35 to both sides:
5x = 215
Divide both sides by 5:
X = 43
Now replace x with 43 in the equation for angle b:
2(43) -12 = 86-12 = 74 degrees
Angle B = 74 degrees
Answer:
5 cakes
Step-by-step explanation:
13 1/3 ÷ 2 2/3
40/3 x 3/8
= 5 cakes
Answer: 20%
Step-by-step explanation:
To find the total number of problems Emilia solved, we can first add 19 and 76 to get:
19 + 76 = 95
Next, to find how many problems Emilia got correct out of the total, we can use the number of problems correct (19) and divide it by the total number of problems (95) to get:
19 ÷ 95 = 0.2
Finally, to make 0.2 a percentage, we can multiply it by 100 to get:
0.2 X 100 = 20
Therefore, Emilia got 20% of the problems correct.
