The circle has a diameter of 16 inches. What is the area of the circle, rounded to the nearest square inch?
2 answers:
<u>Answer:</u>
Option(c)
The area of the circle is 201 square inch when it has a diameter of 16 inches
<u>Explanation:</u>
Given the diameter of circle is, D = 16 inches,
which when converted to radius, r = D/2 =16/2 =8
so radius will be 8 inches.
The area of a circle is determined by the formula ,
where π = 22/7 and r = 8
Calculating and putting values in the formula
A = =201.1428 sq. inch
= 201 sq. inch (rounded to the nearest)
therefore the area of the circle is 201 square inch

Answer:
(a)6 (b)3 (c)0.5
Step-by-step explanation:
Given a fair die with the numbers 1,2,3,4,5, or 6 on each of its faces.
- Event A is the event of rolling an even number
- Event B is the event of rolling an odd number.
(a)The sample space for the outcomes in this experiment is {1,2,3,4,5,6}
There are <u>6</u><u> </u>outcomes in the sample space.
n(S)=6
(b)
Event A is the event of rolling an even number
Sample space of A = {2,4,6}
There are <u>3</u> outcomes in event A.
n(A)=3
(c)The probability of event A
P(A) =<u>0.5</u> is the probability that you choose an even number.
