I would like to get some information of how to do this...​

Answer:

The area is approximately 30.69 cm^2.

Step-by-step explanation:

To solve this problem, we first have to recognize that the side of the block is a rectangle with a semicircle missing.  This means that to find the area, we must find the area of the rectangle and then subtract the area of the semicircle.  Using the respective formulas, we get the following expression for area:

A = (length * width) - (1/2*pi*r^2)

Now, we must plug in the given values shown in the figure.  The length is 9 cm, the width is 4.5 cm, and the diameter is 5 cm.  However, the formula asks for the radius, which is simply half of the diameter, or 2.5 cm.  

A = (9 cm * 4.5 cm) - (1/2 * 3.14 * (2.5 cm)^2)

Next, we should perform the operations indicated inside the parentheses.

A = 40.5 cm^2 - 9.81 cm^2

Finally, we can subtract the two values (this represents taking away the area of the semicircle from the rectangle).

A = 30.69 cm^2

Therefore, the area of the side is approximately 30.69 cm^2.

Hope this helps!

Roberto’s cat weighed 6 3/4 pounds last year.Then the cat gained 1 1/2 pounds.How much does the cat weigh now?
hammer [34]
Add the gain and the last weight together
new weight = 6 3/4 + 1 1/2
or we can write it as
new weight = 6 + 3/4 + 1 + 1/2

Separate whole numbers and fraction
new weight = 6 + 3/4 + 1 + 1/2
new weight = 6 + 1 + 3/4 + 1/2

Simplify the whole numbers
new weight = 6 + 1 + 3/4 + 1/2
new weight = 7 + 3/4 + 1/2

Equalize the denominators of the fraction
new weight = 7 + 3/4 + 1/2
new weight = 7 + 3/4 + 2/4
new weight = 7 + 5/4

Because 5/4 is improper fraction, change it to mixed fraction
new weight = 7 + 5/4
new weight = 7 + 1 1/4
new weight = 7 + 1 + 1/4
new weight = 8 + 1/4
new weight = 8 1/4

The cat weights 8 1/4 pounds now
