If the wheel does one full turn in 180 cm, that means the wheels circumference is 180. The equation for circumference is:
Circumference = (Pi) x Diameter
(Can't find the symbol for pi)
Now plug in the 180 for the Circumference:
180 = (Pi) x D
Divide by Pi:
57.296 = D
ANSWER:
The diameter is 57 cm
Answer:
21
Step-by-step explanation:
2(7+6)-5
2(13)-5

Yes because angle A is 25 degrees
V=4/3 π•r^3
r=6.9 ft
V=4/3 π• (6.9)^3
V=4/3 π • 328.509 ft^3
V= π•438.012 ft^3
V= 1,375.35768 ft^3
V~ 1,375 ft^3
Given:
Number calories in a 6-inch pizza = 640 calories
For the pizza of 6 inch
For the pizza of 12 inch
Number calories in a 6-inch pizza = 640 calories, therefore:
Substitute:
And solve for x:
Now, Estimate the number of calories in one slice of a 12 inch pizza:
Answer: 320 calories
