Answer:
answer is b
Step-by-step explanation:
C= 11pi
⇒ d* pi= 11* pi
⇒ d= 11
The diameter is 11~
The answer is 2/3. Since you need our denominator to be 3 just find a number that divides 12 three times. Since 12/4 is 3 you have your denominator and because you used 4 on the denominator you must do it on the numerator so 8/4 is 2.
I hope I helped!
As according to PEMDAS, the step you should do first is (4+16) since it is in parentheses. Then, you do multiplication and division (order does not matter really, the two operations are on the same level so you just solve left to right) and addition and subtraction (order does not matter really, the two operations are on the same level so you just solve left to right).
