Anyone know how to do this? ! don't leave me hanging! i have picture attached! can somebody show me how to do this! i'm doing a unit test and need asap!

this figure shows circle o with chords pm and ln .

mpl=10∘
mlm=14∘
mln=24∘
pm=15 in.

what is ln?

ln is equal to pm?  

Step-by-step explanation:

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

it is a secret for it not to be compromised sorry
