Sam wants to find the best buy on cans of tuna. He reads these four ads in the newspaper.$12.53 for seven cans$5.97 for three ca
grandymaker [24]
In each case divide the price by the number of cans.
The best buy is the lowest price.
$12.53/7 = $1.79
$5.97/3 = $1.99
$7.95/5 = $1.59
$8.34/6 = $1.39

The fourth ad, $8.34 for 6 cans results in the lowest price per can, $1.39.
The fourth ad is the best buy.

What is the difference in the area of a circle with diameter 4m and a circle with diameter 6m?
nordsb [41]

Answer:

The difference between the area of the two circles is 15.7m

Step-by-step explanation:

I swear these be helping me with the CIEs coming up in May xD

Okay so the formula for a circle is \pi r^2

The diameter is the double of the radius so

Cirlce A has a diameter of 4m so a radius of 2m

\pi 2^{2}

\pi4

12.57m

Circle B has a diameter of 6m so a radius of 3m

\pi 3^2

\pi 9

28.27m

To find the difference subtract 12.57 from 28.27

28.27-12.57\\=15.7

The difference between the area of the two circles is 15.7m

Hope this helps, if you still need help just comment :)
