What is the circumference of this circle r= 2km

Mathematics
1 answer:
gladu [14]3 years ago
7 0

Answer:

6.28 km

Step-by-step explanation:

The formula for circumference is C = 2πr. Just plug in the radius. C = 2π2. 2 times 2 is 4. So, multiply 4π, which is 6.283185307 (rounded to the nearest billionths). Generally, you are supposed to round to the nearest hundredth. The 3 would round the 8 down, leaving 6.28. The unit used to measure the radius, so unless told otherwise by the problem, stick to km. This results in 6.28 km being your final answer.

Answer:

t=1p

Step-by-step explanation:

this problem is fairly easy. we will first do is set the equation to equal t also known as the total price. this is because you were trying to determine how much you will have to pay if she buys her food in bulk. you will then equal t to how much it will cost if the food is in bulk. to do this you will multiply 1 (this next she wants to buy weighs 1 kg) and multiply it by p (price per kilogram).
