As AB is a diameter, then m∠CBA=180^{0}-75^{0}=105^{0}.
∠CBA is a central angle, so its measure multiplied by radius is the length of arc AC.
Note that
and
. Then
and length of the arc is
.The correct answer is 22 in.
Answer:
12
Step-by-step explanation:
Volume= pi x radius squared x height
substitiute values
540π= π x r^2 x 15
divide 540π by π and 15
so thats 36= radius squared
so the radius is 6 as 6 squared is 36
so the diameter is radius x2
so the answer is 12
Answer:
What are the coordinates for point C?
Answer:
<em>( - y - 3 , - x - 1 ) </em>
Step-by-step explanation:
( x , y ) ----> ( - y , x ) ----> ( - y - 3 , x + 1 ) ----> <em>( - y - 3 , - x - 1 )</em>
There are 180 Degrees in a triangle, you know two, 90 and 79, so the last angle is 11
180-90-79=11
