Answer:  An estimate done quickly: The circumference is about 75 ft.
Step-by-step explanation:
Round π to 3, and 24 to 25.  3 times 25 is 75
A more exact value would be 75.36
3.14 × 24 = 75.36
 
        
             
        
        
        
Answer:
$1.53
Step-by-step explanation:
The computation of the change in the bill is shown below:
Total money he has to pay is 
= $8.33 + $2.25
= $13.47
And, he have  
= $10 + $5
= $15
So, the change would be
= $15 - $13.47
= $1.53
 
        
             
        
        
        
Answer:
(2×3)¹ 
(11×1)¹
Step-by-step explanation:
2×3=6 so 2 to the power 1 is 2 and 3 to the power 1 is 3 so 2×3=6
11×1=11 so 11 to the power 1 is 11 and 1 to the power 1 is 1 so 11×1 =11
 
        
             
        
        
        
Answer:
26
Step-by-step explanation:
To evaluate this expression, all we have to do is substitute the given values of the variables into the expression. That is, replace every  in the expression with a
 in the expression with a  and every
 and every  in the expression with a 5.
 in the expression with a 5.
Doing so, we get:
