Yes because if you divide the area by the average radius of the square you get the ration of the pie which in short is 3.14 which you then multiply by the diameter of the average of the blue rectangle and end up getting yes as your answer.

Hope that helped tell me if I need to go to further detail

Answer:

$E = 30 \times H$

$570

Step-by-step explanation:

Given that:

For each hour of tutoring, Lena earns 30 dollars.

E is her earning and

H is the number of hours for which she tutors.

To find:

Equation relating E to H.

Solution:

Let Lena tutors for 1 hour, then the earning = 30 dollars

Let Lena tutors for 2 hours, then the earning = 30+30 OR 2 $\times$ 30 = 60 dollars

Let Lena tutors for 3 hours, then the earning = 30+30 +30 OR 3 $\times$ 30 = 90 dollars

If Lena tutors for H number of hours, then the earning, E = 30 + 30 + .... + 30 (H times) i.e.

$E = 30 \times H$

So, the equation that relates E to H is given as:

$E = 30 \times H$

Now, it is given that she tutors for 19 hours.

Let us put H = 19 hours in the above equation:

$E = 30 \times 19 \\\Rightarrow E = \$570$

Therefore, the earning for 19 hours of tutoring is <em>570 Dollars.</em>

What will happen to the volume of a cylinder if the radius is halved?

Snowcat [4.5K]

Answer:

A. 1/4 as large

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

Cut the radius in 1/2

V = pi (1/2r)^2 h

V = pi (1/4) r^2 h

V = 1/4 pi r^2 h

The volume is 1/4 what is was before we cut the radius in 1/2

What is the combined length of all the buttons longer than 1 inch

muminat

Answer:

$2\frac{1}{2}$ inches

Step-by-step explanation:

The "x" represents the number of buttons.

There are 2 sizes longer than 1 inch:

$1\frac{1}{8}$ in and $1\frac{1}{4}$ in

There are NO 1 1/8 inch buttons

THere are two 1 1/4 inch buttons

Hence the combined length would be:

$1\frac{1}{4}+1\frac{1}{4}=2\frac{2}{4}=2\frac{1}{2}$ inches
