Answer: B
Step-by-step explanation:
The area of a circle is pi*radius^2. But only a diameter is given, so in order to find the radius, you must divide the diameter by 2:
3.6/2 = 1.8
Now, you can plug the radius, 1.8, into the equation pi*radius^2 (
):
= about 10.18
Lastly, you must divide the area 10.18 by 2 because you are looking for only half the area.
10.18/2 = 5.09
Answer:
1200
Steps to answer the problem:
1/5 of a minute goes in to 1 minute 5 times
5 x 240 = 1200
Complementary angles add up to 90o.
The complement of 21 is 90 - 21 = 69
