A circular city plaza is surrounded by a row of bricks. The area of the plaza is 1,520 square meters. How long is the row of bri

Korolek [52]

Answer:

138 meters

Step-by-step explanation:

step 1

Find the radius of the circular city plaza

The area is equal to

$A=\pi r^{2}$

we have

$A=1,520\ m^2$

$\pi =3.14$

substitute

$1,520=(3.14)r^{2}$

solve for r

$r^2=1,520/3.14\\r=22\ m$

step 2

we know that

To find out how long is the row of bricks, determine the circumference of the circular city plaza

The circumference is equal to

$C=2\pi r$

we have

$r=22\ m$

$\pi =3.14$

substitute

$C=2(3.14)(22)=138\ m$
