In a circle with a radius of 8 ft, an arc is intercepted by a central angle of 3π4 radians.
2 answers:
We know that the length of a circumference=2*pi*r for r=8 ft the length of a circumference=2*pi*8---------> 16π ft if 2π radians (full circle)-------------------> has a length of 16π ft 3π/4 radians-------------------------------> X X=3π/4*16π/2π-------------> X=6π<span> ft the answer is 6 </span>π ft
Answer:
(C) .
Step-by-step explanation:
It is given that In a circle with a radius of 8 ft, an arc is intercepted by a central angle of radians. Then the length of the arc is given by:
Length of the arc=radius×angle in radians
⇒Length of the arc=
⇒Length of the arc=
Therefore, the length of the arc is .

Answer:
Volume of cone = (1/3) * Volume of cylinder
Step-by-step explanation:
Use the formulas
Volume of cone = (1/3)* π r^2 *h
Volume of cylinder = π r^2 *h
Therefore
Volume of cone = (1/3) * Volume of cylinder
