Answer:
In one second it turns 200 / 60 = 3 1/3 revolutions. Since one revolution is 360°, the answer is 6 2/3 π radians.
2/3 and 12/18 are equivalent fractions, and 12+18 = 30 so the answer is 12:18
Answer:
A
Step-by-step explanation:
Find the volume of both shapes.
Cylinder - V = πr²h = π·2²·4 = 50.26548
Sphere - V = 4/3πr³ = 4/3π·2³ = 33.51032
Find the difference between the two.
50.26548 - 33.51032 = 16.75516, or 16.75

Answer:
the area is 52.49
Step-by-step explanation:
triangle
radius is 3.5
3.5x19=66.5÷2=33.25
hemisphere
π3.5squared=38.48
38.48÷2=19.24
33.25+19.24= 52.49
If the old man walks 2/3 of a mile in 1/2 an hour, you can find how many miles he walk in one hour by setting up a fraction where distance (miles) is the numerator and the denominator is time (hours). So, (2/3)/(1/2) is the fraction. Now, we have to figure out how to make the denominator one, and we do that by multiplying is by 2. Whatever you do to the denominator you have to do to the numerator, so multiply 2/3 by 2 and 1/2 by 2.
(1/2) x 2 = 1 and (2/3) x 2 = 4/3 or 1 1/3
the old man walked 1 1/3 miles per hour
