If the question is how much Cody will jog to save ratio 4miles:3 miles
The ratio is
We can just multiply 1 miles by ratio to see how much Cody will jog, so
miles
The result is
miles
1) The perimeter is the sum of the lengths of the straight edge (the diameter of the semicircle) and the length of the arc of the semicircle.
The circumference of a 4 ft circle is
π*diameter = π*4 ft ≈ 12.566 ft
The semicircle will have a length that is half that, 6.283 ft. When this length is added to the diameter, the perimeter is found to be
Perimeter = 4 ft + 6.283 ft ≈ 10.3 ft.
2) The area of a circle is given by the formula
A = (π/4)d²
For a diameter of 15 inches, the area is
A = (π/4)(15 in)² = 56.25π in²
A ≈ 176.7146 in²
The area of the circle is about 176.71 in².
Answer:
30 is the wrong one because it is not a factor of 100
30 60 90 120
20 40 60 80 100
Step-by-step explanation:
Answer:
79.5 in ^3
Step-by-step explanation:
5 times 8 times 2.
40 times 2 equals 80.
2 times 1 times .25 equals .5
80-.5 equals 79.5 in^3
