A flower garden is shaped like a circle. Its diameter is 32yd. A ring-shaped path goes around the garden. Its outer edge is a ci

Sergio [31]

Answer:

48 bags

Step-by-step explanation:

step 1

Find the area of the path

we know that

The area of the path is equal to the area of the outer circle minus the area of the inner circle

$A=\pi [rb^{2}-ra^{2}]$

we have

$rb=38/2=19\ yd$ ----> the radius is half the diameter

$ra=32/2=16\ yd$ ----> the radius is half the diameter

$\pi =3.14$

substitute

$A=3.14 [19^{2}-16^{2}]$

$A=329.7\ yd^2$

step 2

Find out the number of sand bags needed

we know that

One bag of sand can cover 7 yd^2

Divide the total area by 7 to determine the number of bags

$A=329.7/7=47.1\ bags$

Round up

$48\ bags$

Original price of a cell phone is 154.99$ the discount is 20% what's the price off

Irina-Kira [14]

To get 10 % you have to divide by 10 .
so 154.99 ÷ 10 = 15.499.
that's 10% but you want 20% so you times 10% by 2.
15.499 X 2 = 30.998.
154.99 - 30.998 = 123.992.
you then need to round the answer so you get $123.99
Hope this helps!!
