If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. You can also work out the circumference of a circle if you know its radius.
Hello There!
First let me say this. I did not like how this question was worded I am a tutor in math and I had to read this problem over and over 5 times. It was confusing but I managed to figure it out. The answer is 61%
My work is shown on paper
Im assuming the base of the triangle is 4cm. The volume is

.
If the dimensions are tripled, the base is 12, the height is 24, and the length is 18. The volume is

, which is 27 times bigger.
If you are increasing each side by a factor of x, you are multiplying the original by
350 gallons for 9
Car with 15 gallons is 427.5 miles and a motorcycle with 5 is 320 so he is wrong
Answer:
Step-by-step explanation:
Use FOIL method
(x + 6)(x +6) = x*x + x*6 +6*x + 6*6
= x² +<u> 6x + 6x</u> + 36 {add like terms}
= x² + 12x + 36
