Answer:
Area of whole circle, i.e. 360 degrees = π(8.91)(8.91) = 79.3881 sq. cm
Area of 1 degree = 0.2205225 sq.cm.
Area of 81 degrees = 17.8623225 sq.cm.

Answer:
-7/10
Explanation:
Substitute x with 3 first and you’d get 3/10(3(4)+9)-7. 3(4) is 12 plus 9 is 21. 3/10 multiplies by 21 is 6 3/10. 6 3/10 minus 7 is -7/10
The pathway is 8.46 yards.
<h3>How to find the length of the pathway?</h3>
To find the length of the pathway, it is required to find how long is the diagonal line from one corner of the herb garden to the opposite corner. As shown in the image attached.
The general formula for this is:
- d = a√2 or diagonal = side√2
Let's apply this formula:
- d= 6 √2
- d= 6 x 1.41
- d= 8.46 yards
