A student needs to make a circular cardboard piece with an area between 154 square inches and 616 square inches. The function f(
Nezavi [6.7K]
The area of the circle by definition is given by:
 f (r) =  \pi  * r ^ 2

 For f (r) = 154:
 154 =  \pi  * r ^ 2

 Clearing r we have:
 r ^ 2 = 154 / 3.14

 r =  \sqrt{154/3.14} 

 r = 7
 For f (r) = 616:
 616 = \pi * r ^ 2
 Clearing r we have:
 r ^ 2 = 616 / 3.14 r = \sqrt{616/3.14} r = 14
 Answer:
 
a reasonable domain for f (r) is:
 
7 <r <14

Order of Operations
emmasim [6.3K]

Given:

4 + 9 + 16 \div 4 - 8 -3 \times  5

To find:

The number of possible solutions, if the Order of Operations did not exist.

Solution:

We have,

4 + 9 + 16 \div 4 - 8 -3 \times  5

Now,

Case 1:

[4 + 9 + 16] \div [4 - 8 -(3 \times  5)]=29\div (4 - 8 -15)

4 + 9 + 16 \div  4 - 8 -(3 \times  5)=-\dfrac{29}{19}

Case 2:

[4 + 9 + 16] \div  (4 - 8 -3) \times  5=29\div  (-7\times 5)

4 + 9 + 16 \div  (4 - 8 -3) \times  5=-\dfrac{29}{35}

Case 3:

4 + 9 + (16 \div 4) - 8 -(3 \times  5)=4+9+4-8-15

4 + 9 + (16 \div 4) - 8 -(3 \times  5)=-6

Many more possibilities are there.

Therefore, there are more than 3 possible solutions.
