The diameter of a circle measures 26m. What is the circumference of the circle? Use 3.14 for , and do not round your answer. Be sure to include the correct unit in your answer.

81.64 meters

Step-by-step explanation:

The formula for circumference is C=2πr. In your case, you will use 3.14 instead of π. The diameter is 26m, which should be divided by 2 to get the radius.

26/2=13

Then, plug everything in the formula:

C=2×3.14×13

C=81.64m

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
