Find the separate areas.
We have a triangle with base 5 cm and height 5 cm, calculate the area:

Plug in what we know:

Multiply:

Now for the two quarter circles, we know that if we put these two together we will end up with a semi-circle with radius 5 cm. The formula for the area of a circle is:

A semi-circle is half of a whole circle, so the formula for the area of it must be:

Now plug in what we know(use 3.14 to approximate for pi):

Simplify the exponent:

Multiply:

Now add this to the area of the triangle to find the approximate area of the entire figure(round to the nearest tenth):
The mean for the second week increased by $0.40.
The mean for the first week is found by adding the data points and dividing by 5:
(12.99+10.50+9.89+6.90+7.58)/5 = $9.57
Since the cost increased by $2 the second week, we add two to the data points before dividing by 5:
(12.99+10.50+9.89+6.90+7.58+2)/5 = $9.97
To find the increase in means, subtract them:
9.97-9.57 = $0.40.
