Answer:
100π or about 314.16
Step-by-step explanation:
The formula for the area of a circle is (pi)*(radius^2)=area.
The radius is 10, so plugging that in you get pi*10^2=area.
Simplifying, you get Area=100π, or about 314.16

Answer:
B.
Step-by-step explanation:
The original equation is cos 64 = 32/k. To solve for k we need to isolate it. we can multiply by k then divide by cos 64. This gives us the equation k = 32/cos 64. Therefore, B is the right answer.
The answer to your question is C)26
Y=-3/2 + ?
21/2=-3/2 + ?
-?= -3/2-21/2
-?= -24/2
-?=-12
?=12
The equation is y=-3/2x + 12
