Evaluate C(7, 4) 35 210 5,040

Mathematics
1 answer:
qwelly [4]3 years ago
4 0

We can use combination formula

C(n,r)=\frac{n!}{r!(n-r)!}

we are given

C(7,4)

so, n=7 and r=4

now, we can plug this value

and we get

C(7,4)=\frac{7!}{4!(7-4)!}

C(7,4)=\frac{7!}{4!\cdot \:3!}

=\frac{7\cdot \:6\cdot \:5}{3!}

=\frac{210}{6}

C(7,4)=35.............Answer

I have a square with a side of 5.25 in. There is a circle inside this square that is big enough to touch all four sides. What is
DENIUS [597]

Answer:

5.9125in^2

Step-by-step explanation:

Step one:

Given data

Dimension of square= 5.25 in

Area of sqaure= 5.25^2= 27.5625  in^2

We are told that the sides of the circle touch the sides of the square

hence the diameter of the circle is 5.25in

radius= 5.25/2= 2.625 in

Area of  circle= πr^2

Area of circle = 3.142*2.625^2

Area of circle=3.142*6.890625

Area of circle= 21.65 in^2

Step two:

The area that is not inside the circle

=Area of square-Area of circle

=27.5625- 21.65

=5.9125in^2
