Step-by-step explanation:
the answer is a as proven by the othee options being false
We know that
360°/12 hour-----------> 30°/hour
<span>Central angle at 4 .00 is 120 degrees
the radius of a clock is 6/2-----> r=3 in
length of a circumference=2*pi*r-----> 2*pi*3----> 18.84 in
the minor arc at 4 .00 is for a central angle of 120</span>°
so
if 360° (full circle)---------> has a length of 18.84 in
120°----------------------> X
X=120*18.84/360-------> X=6.28 in
the answer is
6.28 in
Answer:
A. Cecelia method is exponential becuase the number of minutes increased by an equal number every week
Step-by-step explanation:
Celelias study method went from 20 to 30 to 40 to 50 on the other hand Christopher's method went from 5 to 10 to 20 to 40 my personal thought would be that Cecelias method increased by a equal amount
Correct me if I am wrong ...
Have a great day! :)
Volume of cylinder
πr^2h
π6^2x11=396π
Volume of sphere
4/3πr^3
4/3π6^3=288π
396π+288π=684π
=2148.849375
