Pi is simply the ratio of the circumference to the diamater, what that means is<span>π=<span>Cd</span></span>(C is circumference, d is diameter) or, likewise<span>πd=C</span>So the circumference for your ice-cream cone is simply<span>πd=3.14∗2.25=7.065=C</span>So the circumference is 7.065 inches.
Answer:
160
Step-by-step explanation:
you need to multiply the ounces of gas by 4 like you did to the oil.
First add y to both sides to get 9x=45+y than subtract 45 from both sides to get 9x-45=y or y=9x-45
A: One solution- a=11 b=5
B: Has no solution- a=10 b=5
C: Infinite solution- a=10 b=-8
Answer:
The side lengths cannot belong to a right triangle.
Step-by-step explanation:
This is a simple case of Pythagorean proof. If this triangle was a right triangle, 20^2 + 21^2 = 28^2. However, this is not the case. 20^2 + 21^2 = 841, which square root is 29.
If you forgot, the Pythagoren Theorem is: a^2 + b^2 = c^2.
Hope this helps!
