NEED HELP ANSWER ASAP PLZ 1.the diameter of a sphere is 10.8 . calculate the spheres volume. use 3.14 for pie and round your answer to the nearest tenth. 2.a manufacturer makes decorative Globes out of silver in the shape of a sphere. suppose each sphere has a radius of 1.5 cm. if silver is 8$ per cm^3 how much will it cost to make one solid sphere?.3.14 as pie and do not round answer

1. 659.25

Step-by-step explanation:

1. V = *pi

   radius = diameter * 0.5 = 10.8 * 0.5 = 5.4

   (4*5.4*5.4*5.4*3.14)/3 = 659.25

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
