The formula for the volume of a cylinder is V= a X h
Where a is the are of base and h is height. The base is a circle, so a= pi r^2
471=3.14 (r^2)(6) Divide both sides by 6, then 3.14
25 =r^2 Your next step would be to find the square root of 25
5=r Now you know the radius of the circle, but it asks for diameter. The radius is half of the diameter, so 5 X 2= 10. Your answer would be 10

V= pi * r^2 * h
471 = 3.14 * r^2 *6
471 = 18.84 * r^2
25 = r^2
Sqrt25 = r
5 = r
D= 2*5
D= 10in

Answer:

a

Step-by-step explanation:

given

3(x - 2) < 18 ← distribute the left side

3x - 6 < 18 ( add 6 to both sides )

3x < 24 ( divide both sides by 3 )

x < 8 → a

The following formula relates the temperature in Celsius (C) and the temperature in kelvins (K).

Mademuasel [1]

Answer:

a. K=300.15

b. 300 Kelvin is greater

Step-by-step explanation:

a. If C=23. Place it in C=k-273.15

K=C+273.15 = 27+273.15

K=300.15

b. Put C=25, K=C=273.15

K=298.15 which is lesser than 300 Kelvins

An article reports "attendance dropped 7% this year, to 6854." What was the attendance before the drop? (Round your answer to th

Masja [62]

Answer:

7370

Step-by-step explanation:

Let x represent attendance before drop.

We have been given that an article reports attendance dropped 7% this year, to 6854. We are asked to find the attendance before the drop.

Since attendance dropped by 7%, this means that attendance after drop was 93% of x.

We can represent this information in an equation as:

$x-\frac{7}{100}x=6854$

$x-0.07x=6854$

$0.93x=6854$

$\frac{0.93x}{0.93}=\frac{6854}{0.93}$

$x=7369.89247$

$x\approx 7370$

Therefore, the attendance before drop was 7370.
