Type the correct answer in the box. assume π = 3.14. and round your answer to the nearest hundredth. at the rate of $2.00 per square foot, the cost of painting the rectangular board with a semicircular top shown in the figure is $.

Answer:

The cost of painting the rectangular board with a semicircular top is $31.065 to the nearest hundredth.

Step-by-step

How to find the area of the composite figures?

To find area of the composite figures,

Separate the figure.

Calculate the are of the each figure by which the composite figure is made of.

Add the area of all the individual figures to get the total area of composite figures.

The dimentions of the rectangle is 3 by 4 foot. The area of the rectangle is,

The radius of the semicircle is 1.5 m. The area of the semicircle is,

The area of the composite figure is,

The rate of  painting is $2.00 per square foot. Thus the cost to paint the figure is,

Hence, the cost of painting the rectangular board with a semicircular top is $31.065 to the nearest hundredth.

The total nom of  code that can be used is equal to 5+3 = 8

The answer is in the image 

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

The solution is given in the image below

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
