<h3>
Answer: 128.74 square meters</h3>
=========================================================
Explanation:
The area of the garden only (ignore the circular pathway) is approximately
A = pi*r^2
A = 3.14*20^2
A = 1256
The area of the garden plus the path is approximately
A = pi*r^2
A = 3.14*21^2
A = 1384.74
Notie how I added on 1 meter to increase the radius to 21
Subtract the two circle areas to get the area of the circular ring.
1384.74 - 1256 = 128.74
The units for all of the areas mentioned are "square meters".
Answer:
She had a success rate of 60 %.
Step-by-step explanation:
In order to calculate her percentage of success we need to take the total amount of shots she made and divide it by the total amounts of shots she attempted and multiply it by 100. Since she took 25 shoots and made 15, we have:
percentage of success = (15/25)*100% = 0.6*100% = 60 %
She had a success rate of 60 %.
