Hi there! The answer is 100πcm^2
The radius of a circle can be found by dividing the diameter by 2. In other words : the radius is half of the diameter.
Therefore, the radius of a circle with a diameter of 20 cm is 10 cm.
The exact area of a circle can be found using the following formula:

In order to find our answer, we need to plug in the data from the question.

Hence, the answer is 100πcm^2.
Answer:
$2220
Step-by-step explanation:
Step one
Given data
Principal= $2000
rate= 1.1%= 0.011
time= 10 years
<u>Required</u>
<u>The final amount A</u>
Step two;
For simple interest, the final amount is given as
A=P(1+rt)
substitute
A=2000(1+0.011*10)
A=2000(1+0.11)
A=2000(1.11)
A=2220
$2220
