Answer:
Surface area of sphere = 4πr²
r = radius
and radius = diameter/2
radius = 13/2
= 6.5cm
Surface area = 4 × π × 6.5
= 26 × π
= 81.68
= 81.7cm²
Hope this helps.
6,612 is the answer because all you need to do is combine them by their place value.

Answer: 
Step-by-step explanation:
If we draw RP and PS, then in the quadrilateral formed, we know that
, and since angles in a quadrilateral add to 360 degrees, this means
.
Thus, arc RS also measures 126 degrees
Do it according to the order of operations
(P)E^MxD/A+S-
the answer would be -13
