Answer:
I think it might be 30pi m or 94.2 m.
Step-by-step explanation: So you are finding the perimeter of the circle. You have a radius of 15, the perimeter for a circle is C=2pir. Now we can do C=2pi(15). The answer is 30pi or C=2 x 3.14 x 15= 94.2 Hope this helps.
Answer:
4.64
Step-by-step explanation:
X^2= r/s
4/5+18/x=8
18/x=8-4/5
18/x=36/5
90=36x
x=5/2
Our Order of Operations looks like this:
Parenthesis
Exponent
Multiplication/Division
Addition/Subtraction
Multiplication and division are on the same "level".
When we see them in the problem, we execute the operations from LEFT TO RIGHT. So Shawna should have applied the division before multiplying the 2 and 3. (Because the division is the leftmost operation in the problem).
