Work out the volume of this sphere?
ale4655 [162]

Answer:

1436.8 cm^3

Step-by-step explanation:

You just plug it in:

r = 7 since it is the radius

Volume = (4 / 3) pi x r^3

Volume = (4 / 3) pi x (7)^3

Volume = 1436.75 = 1436.8 cm^3 (nearest tenth)

Given two terms in artimetic sequence find the common difference, the 52 term, and the explicit formula. A15=139 and A30=259
quester [9]

139, 149, 159, 169, 179, 189, 199, 209, 219, 229, 239, 249, 259.


The common difference is 13.


Let n = 52


Let d = common difference


a_52 = 139 + (52 - 1)(13)


a_52 = 139 + (51)(13)


a_52 = 139 + 663


a_52 = 802
