Answer:
The bigger pizza has a diameter of 14 inches, or a radius of 14 / 2 = 7 inches.
The smaller pizza has a diameter of 12 inches, or a radius of 12 / 2 = 6 inches.
Step-by-step explanation:
The area of a circle is πR2 where R is the radius.
The difference in the size of the pizzas is
Area of bigger pizza - Area of smaller pizza
= π(7 inches)2 - π(6 inches)2 = = 49π inches2 - 36π inches2 = 13π inches2
You bought 3 potatoes
3.45/1.15
= 3
To check:
3.45/3
=1.15
Hope this helps!! :))
Answer:
3x^2

The missing term is the product of x and 3x.
x * 3x = 3x^2
Answer: 3x^2
14+4k=2-2k
4k+2k=2-14
6k=-12
k=-12/6
k=-2
sorry if I'm wrong
