I am assuming that you will need to find the circumference of the circle.

Here is the original formula for finding the circumference using diameter:

C= πd

Because we should use 3.14 for pi and we are given the diameter our problem will now look like this:

C=3.14(15)

By multiplying these two together, our answer will be:

B. 47.1

Hope this helps!

Show all work! I don't understand this! Brainleist!<br>I attached a picture this time!

Answer:

2.94 seconds.

Step-by-step explanation:

The ball will hit the ground when the height of the ball is 0 meters.

The equation is...

h = 61 - 6t - 5t^2.

-5t^2 - 6t + 61 = 0

5t^2 + 6t - 61 = 0

We can use the quadratic formula to solve.

[please ignore the A-hat; that is a bug]

$\frac{-b ± \sqrt{b^2 - 4ac} }{2a}$ , where a = 5, b = 6, and c = -61.

= $\frac{-6 ± \sqrt{6^2 - 4 * 5 * (-61)} }{2 * 5}$

= $\frac{-6 ± \sqrt{36 - 20 * (-61)} }{10}$

= $\frac{-6 ± \sqrt{36 + 1,220)} }{10}$

= $\frac{-6 ± \sqrt{1,256} }{10}$

= $\frac{-6 ± 35.44009029}{10}$

Since time cannot be negative, we will not minus the 35.44009029.

(-6 + 35.44009029) / 10 = 29.44009029 / 10 = 2.944009029

That is approximately 2.94 seconds.

Hope this helps!

A tree grew from 4 ft. to 12 ft. in<br> 3 years. What is the percent of<br> increase?

katrin [286]

Answer:

Percent increase is a percent change that describes an increase in quantity

To determine percent increase we first find the amount of change

It is given:A tree grew from 4ft to 12ft in 3 years .

Amount of change =12-4=8 ft.

We use proportion to find percent increase.

Or ,

Cross multiplying we have:

4 ( percent Increase )= 800

Dividing by 4 we have Percent change = 200

Percent Increase = 200%.
