Answer:
15.597 mm^2
Step-by-step explanation:
The formula for circumference of a circle 2πr, in which r is the circle's radius.
The formula for area of a circle π. This means that we can find the radius from the circle's circumference and use it to find the area.
First we have to equal 14 to 2πr because both are representations of circumference and we need to find r.
14 = 2πr
Solve:
14/2 = 2πr/2
7 = πr
7/π = πr/π
2.23 = r
Plug 2.23 into the formula for area as r and solve:
π(2.23)^2
π4.96
15.597
Answer:
24
Step-by-step explanation:
there are 6 seats and 3 boys, 3 girls.
First seat can be given to either boy or a girl.
So there are two ways.
If a boy is selected say, then he has to occupy 3rd and 5th only.
There are 2 ways
Now available positions are 2nd, 4th and 6th, in this girls can be arranged in 3! ways = 6
So total number of ways =
<em><u>The reciprocal property is:</u></em>
<em><u>Solution:</u></em>
Given that,
<em><u>The reciprocal property is given as:</u></em>
The reciprocal of a fraction is the numerator and denominator switched
Therefore,
By reciprocal property,
Switch the numerator and denominator of right side fraction as well as left side fraction
The we get,
Thus option C is correct
