2pi(r)
2x3.14x19
Or 3.14xdiameter(38)
Which is 119.32 or A
278 is rounded to 280 (to the tenth). Anything that is above 5 you right. In case this is 8 so you round. If it is below 5 then you do not round.
Answer:
A
Step-by-step explanation:
Because u are dividing.
Answer:
y
Step-by-step explanation:
y
Try to rewrite the equation;
You know that 5 can be written as log3(3^5)
log3(3^5)=log3(x^2+18) <-- you can now cancel out log3
3^5=x^2+18
243-18=x^2
225=x^2
√225=x
+-15=x
You see that even if x is negative, the squared will always give a positive answer. Therefore, +15 and -15 are both possible answers.
Hope I helped :)
