Solve for r
4r-3=3(3r+4)

-3

this is negative three because of math

r=-3

Step-by-step explanation:

multiply the 3(3r+4) that gives you 9r+12 on that side

subtract 4r from the other side and from 9r and you are left with -3=5r+12

subtract 12 from that side and from -3 and you get -15=5r

divide -15 and 5r by 5 (here's how it looks --) -15/5 = 5r/5

you get -3=r

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

m∠vru = 80°

m∠urw = 15°
