Find AD.

____________________

Here, Sin θ is 30°

Sin =

Here, θ is 30°

Substituting the values, We get,

∴ Sin ( 30 ) =

Substituting the value of BC as 12, We get,

⇒ Sin ( 30 ) =

Transposing 12 to Left Hand Side, We get,

⇒ Sin ( 30 ) × 12 = AD

Calculating further, We get,

⇒ AD = 6 m

∴ AD = 6 m

The Length of AD is 6 m

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!

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!
