Carla must ice a german chocolate cake. The diameter of the cake is 6 cm. Use the formula A = 3.14 x r2 to find the area of the
cake.
A) 7.07
B) 19.63
Eliminate
C) 20.56
D) 28.26
2 answers:
Diameter = 6 6/2 = 3
Radius = 3 3 to the power of 2 = 9
A = (3.14)(9) = 28.26
The radius(r) is half the diameter. So just plug 3 into the equation A=πr². A=3π². The area is about 29.60 (which I think you meant to write for D).
