Answer:
B
Step-by-step explanation:
Hi,
2πr is the formula for circumference, you know your diameter is 4cm and radius is half of the diameter, so your radius is 2cm.
To find the circumference, you have to multiply 2 by 2 and pie. 2 x 2 is 4. So 4 times pie. B is your correct answer.
I hope this helps :)
Answer:
D
Step-by-step explanation:
I would say D because youre trying to find red and blue so green and brown dont matter to the problem. If 12÷6= 2 then. do 60÷2=30 so they can be drawn about 30 times
Choice (A) has zero slope becsuse her cost doesn't depend on the number of visits.
A = 1/4 * (pi) * d^2
A = 1/4 * (pi) * 8^2
A = 1/4 * (pi) * 64
A = 1/4(64) * (pi)
A = 64/4 * (pi)
A = 16 (pi) in^2
Your answer is 16 pi in^2
