6.28 (equation for circle perimeter is 2πr)
Answer:
r = 1
Step-by-step explanation:
In this question, we have to solve for the vallue of "r". We will use the distributive property shown below to ease our process.
Distributive Property:
a(b+c) = ab + ac
Now, lets solve this:

As we have seen the value of r is "1"
Answer:
120 ft by 180 ft
Step-by-step explanation:
If every inch is 15 feet multiply 8 inches by 15 and then 12 by 15 to get your dimensions
15 * 8 = 120
15 * 12 = 180
120 x 180 feet
Convert to inches if needed.
1440 inches by 2160 inches
Do you mean 0.8 = 8/10 = 80%? Ohhh... then it's 1.25!
Hope this helps!
