Answer:
76.93
Step-by-step explanation:
bc your formula is A=πrsquared so 3.14(π) ×3.5×3.5 bc when it's squared it's the number times itself93
so 3.14×3.5×3.5=38.456
38.456+38.456 because you need the area for both so I added the same number to it or you can multiply by 2 if you want
38.456+38.456=76.93
What does the and 2 mean? Does it mean times two or plus two?
Step-by-step explanation:
