Wesley makes spherical fish tanks with a diameter of 30\text{ cm}30 cm30, start text, space, c, m, end text. A customer requests a smaller tank with half the volume of the tank that Wesley usually makes. What is the approximate diameter of the smaller tank?

v = 4/3 pi r cube

v =4/3 pi r (15) cube

v=4500 pi

v= 45000 pi /2=4/3pi r cube

1687.5=r cube

r =11.9

d =23.8

ans =23.8

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

answer: the first graph
