What kind of percentages? Is increase here's how..... 1. First work out the difference (increase amount) between the two numbers you are comparing. 2. Increase = New Number - Original Number. 3. Then divide the increase by the original number and multiply the answer by 100. 4. % increase = Increase divided by the Original Number x 100.

rachel is frosting the top of two cakes and wants to know which cake will require more frosting. one cake is round with a diamet
siniylev [52]

Answer:

The square cake is larger by 31 in^2

Step-by-step explanation:

A round cake has a circular area on top.

We need to find the radius

d= 2r

8 = 2r

r=4

The area of the circle is pi r^2

A = 3.14 * 4^2

A = 3.14 *16

   = 50.24

The area of the square cake is

A =s^2

A = 9^2

A = 81

The square cake is larger

The difference is Asquare - A round

81 -50.24

30.76

Which is close to 31 in ^2
