Avi's pet hamster chubby loves to run in his hamster wheel. during one "race", avi counts 100 rotations of the wheel. she wants
to know how far chubby ran, so she measures the diameter of the wheel and finds that it is 8 space incheshow far did chubby run
2 answers:
If the diameter is 8 inches, the circumference is 8π inches. So if the pet turned the wheel 100 revolutions the distance traveled is:
d=100(8π) inches
d=800π inches
d≈2513.27 inches
Answer:
Chubby ran a total distance of 6280 cm.
Step-by-step explanation:
Each time the hamster wheel rotates, the distance Chubby runs is equal to the circumference of the wheel.
We can use the formula C = πd to find the circumference of the wheel.
C =πd
=π(20)
=20π
The circumference of Chubby's wheel is 20π cm.
Since the wheel rotated 100 times, the total distance Chubby ran is 100 times the circumference of the wheel:
100 x 20π
= 2000π
2000π = 2000 x 3.14
6280

Answer:
c) 2x⁵ + 11x³ - 5x²
Step-by-step explanation:
f(x) - g(x) = 2x⁵ + 7x³ - (-4x³ + 5x²)
= 2x⁵ + 7x³ + 4x³ - 5x²
= 2x⁵ + 11x³ - 5x²
The answer is C. Hope this helps: D
