Answers

Answer 1

Answer:

Answer:

Part 1) The area is $A=4,069.44\ in^(2)$

Part 2) The circumference is $C=226.08\ in$

Step-by-step explanation:

step 1

Find the area

we know that

The area of a circle (circular tablecloth) is equal to

$A=\pi r^(2)$

we have

$r=72/2=36\ in$ ------> the radius is half the diameter

$\pi =3.14$

substitute

$A=(3.14)(36)^(2)$

$A=4,069.44\ in^(2)$

step 2

Find the circumference

we know that

The circumference of a circle (circular tablecloth) is equal to

$C=\pi D$

we have

$D=72\ in$

$\pi =3.14$

substitute

$C=(3.14)(72)$

$C=226.08\ in$

How to reduce the fraction 16/24

Answers

To reduce the fraction in its simplest form...first find the greatest common factor of the numerator and the denominator..so in this case is 8.

Now lets divide the numerator by the GMF;
16 ÷ 8 = 2
Next the denominator;
24 ÷ 8 = 3

So $(16)/(24) = (2)/(3)$
Hope this helps! :D

First divide by 2 to both top and bottom which is 8/12. Then divide by 2 again which is 4/6. Finally, divide by 2 again which is 2/3.
