In a park, a sidewalk is built around the edge of a circular garden as shown below. The sidewalk is 5 feet wide, and the garden measures 20 feet across. Which measurement is closest to the circumference of the outer edge of the sidewalk?

A.
75ft

B.
90ft

C.
30ft

D.
700ft

B.  90ft

Step-by-step explanation:

-The diameter of the outer edge will be equivalent to the garden's diameter plus twice the sidewalk's width:

#The outer circumference can then be calculated as:

Hence, the measurement closest to this circumference value is 90 ft

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
