Solution:

$$h=\frac{ A-2\pi r^2}{2\pi r }$

Given data:

$A=2\pi r^2+2\pi r h$

Let us determine what is h using given A.

$A=2\pi r^2+2\pi r h$

Subtract $2\pi r^2$ on both sides of the expression.

⇒ $A-2\pi r^2=2\pi r^2+2\pi r h-2\pi r^2$

⇒ $A-2\pi r^2=2\pi r^2-2\pi r^2+2\pi r h$

⇒ $A-2\pi r^2=2\pi r h$

Divide both sides of the expression by $2\pi r$ .

$$\frac{ A-2\pi r^2}{2\pi r }=\frac{2\pi rh }{2\pi r }$

$$\frac{ A-2\pi r^2}{2\pi r }=h$

$$h=\frac{ A-2\pi r^2}{2\pi r }$

Option C is the correct answer.

Hence $$h=\frac{ A-2\pi r^2}{2\pi r }$ .

In a classroom,there are 12 girls and 8 boys.What fraction of the students in class are girls?What percent of the class are girl

tekilochka [14]

Answer:

Step-by-step explanation:

Add the total number of students:

Boys: 8, + Girls: 12 = 20 students

$\frac{12}{20} = \frac{6}{10}$ of the students are girls

6/10 also equates to 60%, which is the percent of girls in the class.

The temperature outside is currently 10°F. It will fall at a constant rate of 3°F per hour. Which temperature will it be in 4 ho

Triss [41]

Answer:

T4 = -2°F

Step-by-step explanation:

Given the following data;

Current temperature = 10°F

Constant, K = 3°F

Time, t = 4 hours

In four (4) hours, we have;

T = kt

Substituting into the equation, we have;

T = 3 * 4

T = 12°F

T4 = current temp - new temp

T4 = 10°F - 12°F

T4 = -2°F

Therefore, the temperature it will be in 4 hours is - 2°F.
