The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A
let me know if you have any questions!!!
Answer: (-2,5)
Step-by-step explanation: just graph both equations they are already set up in the form and find the point where they intersect
Answer:
60% of $70 is $42, so i think its $42
Using change of base
log5/log 625
both logs cancels
then becomes 5/625
+ 1/4
