The required value is the angle theta and the value of the cosine of the angle is 0.9659

Given the expression of sine of an angle expressed as;

$sin\theta = 0.2588$

For us to get the cosine of the angle, we need to get the value of theta first as shown:

$\theta = sin^{-1}0.2588\\\theta = 14.99^0$

Next is to get the value of cos theta

$cos \theta = cos 14.99 =0.9659$

The required value is the angle theta and the value of the cosine of the angle is 0.9659

Nuetrik [128]

Answer:

960.84 in^2

Step-by-step explanation:

The formula for the surface area of a cylinder is ...

SA = 2πr^2 +2πrh = 2πr(r +h)

For the given box, the surface area is ...

SA = 2π(9 in)(9 in + 8 in) = 306π in^2

SA = 960.84 in^2

960.84 square inches of wrapping paper are needed.
