Answer:

Area = 64 + 16\pi

Step-by-step explanation:

Given

See attachment for the heart created

Required

The area of the heart

The area of the heart is the sum of the area of the square and the areas of the two semicircles.

From the attachment, we have:

s = 8in --- length of the square

d = 8in --- diameter of each semicircle

Calculate radius

r = 0.5 * d

r = 0.5 * 8 = 4in

The area of the square is:

Area = Length^2

A_1 = 8^2

A_1 = 64in^2

The area of the two semicircles is:

A_2 =2 * \frac{\pi r^2}{2} i.e. 2 multiplied by the area of 1

A_2 = \pi r^2

A_2 = \pi *4^2

A_2 = \pi *16

A_2 = 16\pi

So, the area of the heart is:

Area = A_1 + A_2

Area = 64 + 16\pi

Square foot is a unit of area. find the area of the manhole. A = (pi)r^2

9.2 lbs per square foot multiplied by area in units of square feet gives lbs.

diameter is twice radius, so radius is 1.5 ft.
Area of manhole = (pi)(1.5)^2
lbs manhole = (9.2)(pi)(1.5)^2
= 65 lbs

Evaluate the expression shown below and write your answer as a fraction in simplest form.
alexandr402 [8]

Answer:

1/20

Step-by-step explanation:

multiply 3/4 by 10 and multiply 7/10 by 4 then subtract fractions

30/40 - 28/40 = 2/40 divide it by 2 so we get the simplest form.

The March family go out for dinner, and their bill comes to $118.40. If they leave a 20% tip, how much is the tip they leave?
erica [24]

Answer:

tip amount = $23.68

Step-by-step explanation:

t = tip percentage (as decimal, so 5% would be 0.05)

c = cost

tip amount = c * t

tip amount = (118.40) * (0.20) = $23.68

hope this helps :)
