PLS HELP ME a geometric series with first term 3 coverage to the sum of 2. find the common ration of the series

(a) -1
(b) 1/2
(c) - 1/2
(d) 1

The common ratio is the number you multiply or divide by at each stage of the sequence. The common ratio is therefore 2. You can find out the next term in the sequence by multiplying the last term by 2.

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

16.80 times .20= 3.36
