If the area of a circle measures 16 pi cm2, what is the circumference of the circle in terms of pi
Fiesta28 [93]

Answer: 8 pi

Step-by-step explanation: So we know that area of a circle is pi times r^2 so if we reverse that formula it would be square root of 16 pi which would be 4 pi and divide by pi so the radius is 4. And we know that the formula for circumference is 2 times pi times r, so 2 times 4 times pi is 8 pi. 8 pi is the cIrcumference! :)

Answer:

(B) 477=6(1+0.20)^t

Step-by-step explanation:

we can use formula

P(t)=P_0(1+r)^t

where

Po is the initial population

r is the growth rate

t is the time in months

We are given

initial population of insects

so, Po=6

The scientists find that the insect population, x, is growing exponentially 20% per month

so, r=0.20

now, we can plug these values

P(t)=6(1+0.20)^t

there to be a population of 477 insects

so, P(t)=477

now, we plug it

and we get

477=6(1+0.20)^t
