Taylor is making a mini apple pie with a radius of 3.14 in for her math class. what is the area of her mini pie?
artcher [175]

So First of all we need to know how to find the area of a circle.

Assuming that the apple pie is the shape of a circle

The formula for area is \pi r^{2}

Well we know that the radius = 3.14

And we know that \pi = 3.14 as well.

All we have to do is multiply..

3.14 x 3.14^{2} = 30.95

So the area of the pie is 30.95 in


Good Luck! :)

Write an equation for this situation.
kirza4 [7]
Answer: A) y = 3x + 2

Step-by-Step Explanation:

Let ‘x’ be the number of months
Let ‘y’ be the total no. of books he read

Given:

He read 2 books before joining (+2)
He plans to read 3 books per month (3x)

Equation:

= Total no. of books = 3 multiplied by the no. of months + 2 books he had read

=> y = 3x + 2

Solve each system by substitution.
mariarad [96]

Answer:

1) (x, y) = (1, 8)

2) (x, y) =<em>(-2, -4)</em>

3) (x, y) = (3, -1)

Step-by-step explanation:

1) Given the equations;

7x+2y =23  .... 1

6x+y= 14  .... 2

From 2; y = 14-6x

Substitute into 1;

From 1; 7x+2y =23

7x + 2(14-6x) = 23

7x + 28 - 12x = 23

-5x = 23 - 28

-5x = -5

x = 5/5

x = 1

Substitute x = 1 into y = 14-6x

y = 14 - 6 (1)

y - 14 - 6

y = 8

Hence (x, y) = (1, 8)

2) Given

y=-4

y=-3x-10

We will simply equate bith expression and get x;

-3x - 10 = -4

-3x = -4 + 10

-3x = 6

x = 6/-3

x = -2

<em>Hence the solution is (-2, -4)</em>

<em></em>

3) Given the equation

y=-3x+8

y=5x-16

Equate both expressions;

-3x + 8 = 5x - 16

-3x - 5x = -16 - 8

-8x = -24

x = 24/8

x = 3

Substitute x = 3 into y=-3x+8

y = -3(3) + 8

y = -9 + 8

y = -1

Hence the solution (x, y) = (3, -1)
