Find the area of the wheel:
Area of a circle is found using the formula:
Area = PI x r^2
9 inch would be the diameter, so the radius would be 9/2 = 4.5 inches.
The area would be 3.14 x 4.5^2 = 63.6 square inches.
Now divide the price by the area to get price per square inch:
Cost per square inch = 18.60 / 63.6 = $0.29 (rounded to the nearest cent)
Transformation.. If you're referring to geometry
Answer:
It will increase by 9 units.
Step-by-step explanation:
We can write the lowest number as 10a + (a + 1) and the highest is the reverse which is 10(a + 1) + a.
Subtracting:
10(a + 1) + a - (10a + a +1)
= 10a + 10 + a - 10a - a - 1
= 10a - 10a + a - a + 10 - 1
= 10 - 1
= 9.
Dividing fractions is the same as multiplying by their reciprocal.
5/24 ÷ 3/16
is the same as
5/24 * 16/3
80/72
simplify
10/9 or 1 1/9
Step-by-step explanation:
volume of prism = 4 1/2 × 4 1/2 × 6
= 9/2 × 9/2 × 6
= 121.5 cm³
storage container = 143 cm³
Difference = 143 - 121.5 = 21.5 cm³
