Diameter = 18 m

D= 2*r

r = d/2

r =18/2

r = 9

Circumference = 2 * pi * r

C = 2 * 3.14 * 9

C = 56.52

Area = pi r^2

Area = 3.14 * 9^2

Area = 3.14 * 81

Area = 254.34

Answer:

Radius=9

Circumference= 56.52 or 56.52

Answers

Answer:

The answer for A. Would be 1 mile B. 2mph C. 4mph and the rest Im still working on

Step-by-step explanation:

a. How far from home was Danielle after 1/2 hour?

According to the graph, after half hour, Danielle was 1 mile far from home.

Therefore, the speed between 0 and 1 hour is 2 miles per hour.

c. What was Danielle's speed between 1 and 2 hours?

The Danielle's speed between 1 and 2 hours is zero (). Because, according to the graph, during this time, Danielle didn't move, and without move, there's no speed.

d. What is the domain when the function is increasing?

The domain when the function is increasing refers to the increasing x intervals.

From the graph, this increasing interval is from 0 to 1 hours only, it's the only period of time when Danielle was increasing her position.

e. What is the domain when the function is decreasing?

The parts of the decreasing domain are:

From 2 to 3 hours.

From 3 and a half to 4 hours.

In the graph, you can see these decreasing intervals, which are characterized by a downwards direction of the line.

f. What is the domain when the function is constant?

The parts where the function is constant:

From 1 to 2 hours.

From 3 to 3 and a half hours.

Constant intervals, means no increase, no decrease, just an horizontal line.

The ratio of flutes to saxophone players in the school band is 6:4 if there are 50 total students how many saxophone players are in the band

Answers

There are 20 saxophone players. For every 6 flutes there are 4 saxophones so if you do 6x5=30. Then you would do 4x5 and get 20. 30 flutes plus 20 saxophones = 50 total students

saying that there are 6 students that play flute for every four that play saxophone.
4+6= 10 and we need 50 so we have to multiply each by 5. 6 times 5 is 30. therefore there are 30 flute students. but we are looking for saxophone! 4 times 5 is 20 so there would be 20 saxophone players.
