Step-by-step explanation:

Q1)
the surface area of the sphere can be calculated using the following equation 
Area = 4πr²
where r = radius
π = 3.142
radius of the sphere = 4 m
substituting radius in the area equation 
Area = 4 x 3.142 x 4²
        = 201.08 m²
when rounded off to nearest sq.meter , 201.08 ≈ 201
answer is C. 201 m²

Q2)
volume of the sphere can be calculated from the following equation
V = 4/3 πr³
 radius of sphere = 6 m
π = 3.142
V = 4/3 x 3.142 x 6³
   = 904.8 m³
rounded off to nearest sq. meter 
904.8 ≈ 905 m³
correct answer is A
