Common difference of an Arithmetic progression can be found out by subtracting the preceding term from that given term.
i.e
therefore, the common difference of the above Arithmetic progression is -4 .
Answer:
Step-by-step explanation:
hello :
here is an solution
The surface area of a sphere of radius r is A = 4π*r^3.
Since the radius in this case is 8 cm (half the 17 cm diameter), the area of this sphere is
A = 4π(8 cm)^2, or 256π cm^2.
The answer would be 4.6 (repeating).
