The correct answer is 23.6
First find the length of the square root of 72 which is 8.4
Next divide 8.4 by the square root of to to find the length of a side 5.9
Multiply 5.9 by 4 to get 23.6
Answer:
A
Step-by-step explanation:
We are given:

Since cosine is the ratio of the adjacent side over the hypotenuse, this means that the opposite side is (we can ignore negatives for now):

So, the opposite side is 5, the adjacent side is 12, and the hypotenuse is 13.
And since θ is in QIII, sine/cosecant is negative, cosine/secant is negative, and tangent/cotangent is positive.
Cosecant is given by the hypotenuse over the opposite side. Thus:

Since θ is in QIII, cosecant must be negative:

Our answer is A.

So, we need to find { curved surface area[pi*d*h] + top area[pi*(d^2)/4] }
just
substitute.
