The radius R of a sphere is 5.4cm. Calculate the sphere's surface area A. Use the value 3.14 for "pie" and round your answer to the nearest tenth
method is the same you need to substitute r=5.4 in, SA=4*3.14*r^2=4*3.14*5.4*5.4=366.3m^2
check the work carefully i thing one of the digits is wrong
is it the last one then make it 2
I don't know what you're talking about but $3.14 is a great value for a pie. I say buy the pie.
