Geometry pls help :(

900 pi for first question and 14137 for 2nd

Step-by-step explanation:

SA=4pi r^2

r=15 (30/2)

SA=4pi(15^2)

SA=900pi

V=4/3pi r^3

V=4/3(3.14)(15^3)=14137

Surface area: 900π in²

Volume: 4500π in³

Step-by-step explanation:

A = 4πr² = 4π(15²) = 900π

V = 4/3 πr³ = 4/3 π(15³) = 4500π

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
