Answer:
Circumference ≈ 50.27
Area ≈ 201.06
Step-by-step explanation:
The circumference of a circle is 
while the area of the circle 
Since the diameter is the radius multiplied by 2, the radius of the circle is 8. So substituting 8 for r, the circumference is 2 × 
× 8, which is approximately 50.27 (rounded to the nearest hundredth) and the area of the circle would be × 8². 8² is 64 so 64 times pi is approximately 201.06 (rounded to the nearest hundredth)
Answer:
97.2
Step-by-step explanation:
multiply the speed value by 3.6
The way you say this is one hundred nineteen ten thousandths if this helps mark brainiest
30, radius is equal to half the diameter, so to get diameter from the radius, multiply the radius by two.
