<h2>Answer:</h2>

C = 2πr

r = C/2π ...(1)

A = πr²

A = π(C/2π)² = πC²/4π²

A = C²/4π.

<u>Correct choice</u> - [A] A = C²/4π.

11. Rocco and Biff are two koalas sitting at the
bagirrra123 [75]

Answer:

Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

Step-by-step explanation:

Let the height of Biff's tree be represented by x, so that the height of Rocco's tree is \frac{x}{2}.

Draw a straight line from Rocco's point of view to a point t to the middle of Biff's tree. This line divides x into two equal parts, and the angle is divided into 35^{0} each.

By alternate angle property,

Tan  35^{0} = \frac{\frac{x}{2} }{10}

\frac{x}{2} = Tan  35^{0} × 10

  = 7.00021

⇒       x = 2 × 7.0021

            = 14. 0042

         x = 14

Therefore, Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

What is the rate of change of the function?
Alona [7]

We have been given that on a coordinate plane a line with negative slope passes through points (0,1) and (1,-1). We are asked to find the rate of the change of the function.

We know that slope represents rate of change of function.

We will use slope formula to solve our given problem.

m=\frac{y_2-y_1}{x_2-x_1}

Let (x_1,y_1)=(0,1) and (x_2,y_2)=(1,-1).

m=\frac{-1-1}{1-0}

m=\frac{-2}{1}

m=-2

Therefore, the rate of change of the given function is -2.

A student recorded her scores on weekly math
alina1380 [7]

Answer:

mean: 7.62

median: 8

mode: 9

Step-by-step explanation:

first you have to put the data set in order:

6,6,6,6,7,7,8,8,9,9,9,9,9

the mode is the most often repeated number in a data set so the mode in this data set would be 9. The median is the middle number in the data set. The middle number in this data set is 8. Lastly, the mean in a data set is all of the numbers in the data set added together and then divided by how many numbers are in the set. The equation for this data set would be 99/13= 7.62

hope this helps!!
