Hello,
Please, see the attached file.
Thanks.
- Diameter = 51 cm
- Radius (r) = 51 cm ÷ 2 = 25.5 cm
- π = 3.14
- Circumference
- = 2πr
- = 2 × 3.14 × 25.5 cm
- = 160.14 cm
- Area of a circle
- = πr^2
- = 3.14 × (25.5)^2 cm^2
- = 3.14 × 25.5 × 25.5 cm^2
- = 2041.785 cm^2
Hope you could understand.
If you have any query, feel free to ask.

We know that the price of all the fabrics is the same. However, the length of the fabrics is different. We have to determine which fabric is the longest.
Option A:
= 8.6
Option B:
= 8.25
Option C:
= 8.6667
Option D:
= 7.33....
Hence, the longest fabric is the one given in option C, and its length is 8.6667
Answer:

Grant will make $60 from selling 12 magazines.
Step-by-step explanation:
Let m represent number of magazine sold and A represent amount of money earned.
We have been given that Grant earns $5 for each magazine he sells. So amount earned from m magazines would be 5 times m that is
dollars.
Now, we will equate total amount earned by Grant with A as:

Therefore, our required equation would be
.
To find the amount earned by Grant by selling 12 magazines, we will substitute
in our equation as:


Therefore, Grant will make $60 from selling 12 magazines.
