Nancy is asked to use her calculator to find the volume of a cylindrical canister that has a radius of 10.55 cm and a height of 12.56 cm. which answer is the most accurate? volume of a cylinder can be calculated using the following equation: v=πr2h a. 4377 cm3 c. 4380 cm3 b. 4379 cm3 d. 4392 cm3

use the formula given:

 V = pi r^2h

 r = 10.55

h = 12.56

 V = 3.14 x 10.55^2 x 12.56 = 4391.81 round off to 4392cm^3

 answer is D 4392

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
