Sandra calculated the height of a cylinder that has a volume of 576(pie) cubic centimeters and a radius of 8 centimeters. her work is shown below.
v=bh
step 1: 576(pie)= (pie)8^2h
step 2: 576(pie) = 64(pie)h
step 3: 576(pie)/64(pie) = 64(pie)/64(pie)h
step 4: h=9(pie) cm
what error did sandra make when calculating the height of the cylinder?
a. in step 1, she substituted into the volume formula incorrectly.
b. in step 2, she calculated 8^2 incorrectly. it should be 16 rather than 64.
c. in step 4, the (pie) should have canceled, making the correct answer 9 cm.
d. sandra calculated the height of the cylinder correctly.
