Answer:
422.16
Step-by-step explanation:
Area of circle
A=π²
(3.14)×(12²)
(12²)=144
(3.14)×(144)=452.16
Area of rectangle
10×3=30
452.16-30=422.16

8it is 8 .......................
Answer:
Store a is 25 cents per ounce, while store b is 33 cents. Therefore store A is a better price per ounce. For eight dollars you can get 32 ounces of granola.
Step-by-step explanation:
The volume of a sphere is calculated through the equation,
V = 4πr³ /3
where r is the radius of the given.
If the radius is 2.86, we can substitute the value to the equation above such that,
V = 4π(2.86)³ / 3 = 97.99π m³
When the radius is 0.09 m plus the given radius then,
V = 4π(2.86 - 0.09)³ / 3 = 89.03π m³
The difference between the volumes is equal to,
difference = 97.99π - 89.03π m³ = 8.96π m³
Dividing this to the original volume and multiplying by 100%,
percentage = (8.96π/97.99π) x 100%
percentage = 9.14%.
Hence, the expected percent uncertainty is equal to 9.14%.
