Help a g in math really need the help

≈ 5.4 cubic metres

Step-by-step explanation:

Answer = V - V1 - V2

V - volume of tub without the 2 cylinders

V1 - volume of the bigger cylinder

V2 - volume of the smaller cylinder

V =  (4/3 π R*3):2 = (4/3 π · (1.5)*3):2 = 2.25π ≈ 7.0685834705770347

R - radius

V1 = S1h1 ≈  1.23 · 0.7 = 0.861‬

S1 = (0.625)*2 ·π ≈ 1.22718463030851298

V2 = S2h2

S2 = (0.375)*2 ·π ≈ 0.44178646691106

*rounding everything to nearest 100th just in case*

7.07 - 1.23 - 0.44 = 5.4

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
