V=πr^2h
V= volume, r=radius, and h=height
Plug in what you know.
1,728= 3.14*r^2*22
Combine like terms.
1,728= 69.08*r^2
Divide both sides by 69.08.
25. 0144759.... Round down to 25.
25=r^2
The square root of 25.
r=5
The radius is about 5 centimeters.
I hope this helps!

<span>For the Vertical Angle theorem, if a slant line is intersected by a horizontal, the opposite angles must be equal. In here, he stated that the sum of angle 1 and angle 4 and the sum of angle 3 and angle 4 are each equal to 180 degrees. It means that the sum of angle 1 and angle 4 is equal to the sum of angle 3 and angle 4 by the transitive property of equality. </span>

Answer:
Step-by-step explanation:
Given that:
Ava bring 34 food to the picnic
Kate bring 16 food to the picnic
JIn brings 112 food to the picnic
To enter these digits by applying equivalent fractions with a denominator of 12;
Their respective numerical expression is:
Ava = 
Ava brought
food to the picnic
Kate = 
Kate brought
food to the picnic
Jin = 
Jin brought
food to the picnic
