Answer:

194\ ft^{2}

Step-by-step explanation:

we know that

The area of the figure is equal to the area of the rectangle plus the area of one circle (Remember that the area of two semicircles is equal to the area of one circle)

step 1

Find the area of rectangle

The area of rectangle is equal to

A=bh

we have

b=8\ ft

h=18\ ft

substitute

A=8*18=144\ ft^{2}

step 2

Find the area of one circle

The area of the circle is equal to

A=\pi r^{2}

we have

r=8/2=4\ ft

\pi=3.14

substitute

A=(3.14)(4^{2})=50.24\ ft^{2}

step 3

Find the area of the figure

144\ ft^{2}+50.24\ ft^{2}=194.24\ ft^{2}

Round to the nearest whole number

194.24\ ft^{2}=194\ ft^{2}

PLEASE HELP PLEASE WILL MARK BRAINLY
Shtirlitz [24]

Answer:

Every 18 miles he uses 3 gallons

divide this:

18 ÷ 3 = 6 miles per gallon

30 miles = 30 ÷ 6 = 5 gallons

7 gallons = 7 x 6 = 42 miles

48 miles = 48 ÷ 6 = 8 gallons

10 gallons = 10 x 6 = 60 miles

Hope this helps :D
