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:
4 in.
Step-by-step explanation:
length times width = area
actually im not really sure lol. we havent done this in a while
Answer:
5 times larger
Step-by-step explanation:
5*10^5 = 500,000
1*10^5 = 100,000
500,000/100,000 = 5
1 meter = 39.370 inches.....so 5 meters = (5)(39.370) = 196.85 inches
Answer:
13,000,000+200,000+60,000
