Step-by-step explanation:
We can immediately elimate two answers since x cannot be larger than the hypotenuse, which is 9. You can cosine = adjaent/hypotenuse, which gives the equation cos(54) = x/9, which simplifies to x = 9*cos(54). When you plug this into a calculator, you should get 5.29. Keep in mind that 54 is measured in degrees and not radians because.
We know that
[surface area of sphere]=4πr²
[surface area of hemisphere]=2πr²
(sphere)
r=12 in
[surface area of sphere ]=4π12²--------> 576π in²
(hemisphere)
r=12 in[surface area of hemisphere ]=2π12²--------> 288π in²
[the ratio of the surface area of sphere to the surface area of hemisphere]
=576π/288π-------> 2
the answer is
the ratio is 2
