Answer:
131.95 cm
Step-by-step explanation:
The Formula for the circumference of a circle is πd where d is the diameter. Therefore you simply multiply 42 with PI to get the circumference
Answer:
103=618/6
0.0097=6/618
Step-by-step explanation:
I'm going to assume the crust covered by the dosenot matter because the total surface area cannot be found without the depth of the pie.
So the surface are is the area of the top of the pie, the top of the pie is circular and is equal to 2
r²
The diameter is the sum of 2 radii, hence r=8
D=12
= 2r =12
r=8
With the raduis the area can be found
A= 2
r²
A=2
8²
A=2(64)
A=128
If the pie cost 10.99, the cost per inch can be found by dividing the area by cost
cost/inch =128
/10.99
cost/inch =11.64
= 11.64(3.14)
= 36.57
The pie costs 36 cents per square inch
Let x be the length and y be the width of a rectangle.
Area = xy
When x and y are doubled
Length = 2x and Width = 2y
Area = 2x x 2y
Area = 4xy

Answer: When the dimension is doubled, the area is 4 times the original.

Store should sell about 31 bicycle for average price of $135 each bicycle.
Step-by-step explanation:
- To find bike we need Algebra to solve the equation.
- when x = 1 , Y = 135 *x
- When x 2 , Y = 135 *2
- Formula you could apply to go for break even y = 135*x
- Bicycle store pays about $4200
- Algebra used for every business and working to make easy task.
- It takes about 31 bicycle a month to get into break even.
- Every store needs break even to not incur lost.
- Break even point is equilibrium between income and expenses.
