Answer:
D
Step-by-step explanation:
27 = P×(1 + 3r) = P + P×3×r
27 - P = P×3×r
r = (27 - P) / (3P)
therefore D is correct
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:
BC = 17
Step-by-step explanation:
l^2+l^2=h^2
