Juan wants to know the cross-sectional area of a circular pipe, He measures the diameter
which he finds, to the nearest millimeter, to be 5 centimeters,
To find the area of the circle, Juan uses the formula A =Tuple where A is the wea of the
circle and r is its radius, He uses 3.14 for a, What value doen Juan ger for the wea of the
circle? Make sure you include your units,

The area is 19.625 cm^2

Step-by-step explanation:

For the area of a circle, the equation is:

A = pi*r^2

where pi = 3.14 and r is the  radius of the circle, and the radius is half the diameter.

We have that the diameter is 5 cm, then the radius is:

r = 5cm/2 = 2.5 cm

Then the area is

A = 3.14*(2.5cm)^2 = 19.625 cm^2

Step-by-step explanation:

Diameter of the Cross-Sectional Area=5 cm

Radius =Diameter/2

Therefore, Radius of the Cross-Sectional Area of the Cylindrical Pipe =5/2=2.5cm.

The Cross-Sectional Area of the cylindrical pipe is .

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

multiply  

3   by   2 . 9 x 4 y 6
