Question

As part of the design of a high performance engine, you are analyzing properties of spherical ceramic ball bearings. Since many ceramic materials are considerably less dense than the metals typically used in such applications, the centrifugal load added by the bearings can be significantly reduced by the use of ceramics. Which of the following could be typed in c B5 and copied across to cell F5 ell then down to cell F to calculate the masses of the various ball bearings shown in the table? If more than one answer is correct, indicate all that apply 4/3 astir PI astir dollarA5^3 astir dollarB4 = 4/3 astir PI() astir dollarA5^3 astir Bdollar4 = 4/3 astir PI() astir dollarAdollar5^3 astir dollarBdollar4 4/3 astir PI() astir AdollarA5^3 astir Bdollar4 4/3 astir PI() astir A5^3 astir B4

Explanation / Answer

A mixed reference has either an absolute column and relative row, or absolute row and relative column. An absolute column reference takes the form $A1, $B1, and so on. An absolute row reference takes the form A$1, B$1, and so on.

So the answer is option (B) =(4/3)*PI()*$A5^3*B$1
