jolli1 [7]

Answer:

Therefore 80 ceperies will he need to sell this month.

Step-by-step explanation:

Average: Average is the ratio of sum of all numbers to the total number present in the data.

Given that Herbert has sold 99, 37, 86 and 73 copeirs in the last 4 months.

Let he need to sell x copeirs in this month.

According to the problem,

\frac{99+37+86+73+x}{5}=75

⇒ 99+37+86+73+x= 75×5

⇒295 + x= 375

⇒x = 375 - 295

⇒ x= 80

Therefore 80 ceperies will he need to sell this month.

How much more pizza is in a 12-in.diameter pizza than an 8-in.diameter pizza?
e-lub [12.9K]

Answer:

62.8 in2

Step-by-step explanation:

With round pizza we need to

find the area of each pizza in

square inches, then determine

the difference.  

The area of a circle is given by:

A = πr2

 

12 inch diameter, radius = 6

a = π(62) = 36π in2

 

8 inch diameter, radius = 4

a = π(42) = 16π in2

 

Difference:  36π - 16π = 20π in2

 

using 3.14 for pi, the difference is

20(3.14) = 62.8 in2
