Answer:

4 times

Step-by-step explanation:

Area of circle A

[tex]\pi \times {r}^{2} = area \: of \: a \: circle \\ \pi = 3.14 \\ 3.14 \times {8}^{2} \\ 3.14 \times 64 = 200.96 \: {cm}^{2} [/tex]

Area of circle B

[tex]\pi\times 4 (because \: radius \: is \: the \: half \: of \: diameter) \\ 3.14 \times 4 square = 50.24\: {cm}^{2} [/tex]

How many times larger is the area of circle A than circle B

[tex]200.96 \div 50.24 = 4[/tex]

therefore circle A is 4 times larger than circle B in accordance with its area
