Answer: (pi) (6 squared)
Step-by-step explanation:
Hi, the base area of a cone is a circle, so, to answer this question we have to apply the next formula:
Area of a circle: (pi) radius^2
The diameter (d) of a circle is equal to: 2 radius
So:
D = 2r
Replacing with the value given:
12 =2r
12/2=r
radius= 6 inches
Back with the Area formula:
A = (pi) 6^2
Feel free to ask for more if needed or if you did not understand something.
Check the picture below.
notice AB ⟂ BC , whilst ∡B = 30°.
now, if we run a perpendicular line from C to AB, it'll be a 90° angle at M, however ∡AMC has to be 105°, so it has to be slanted more towards A, like in the picture, and surely you already know which one is the shortest.
The other person is literally wrong. The answer is D. Supplementary because two angles that add up to 180 are supplementary angles.
