a certain coin is a circle with a diameter of 18mm. What is the exact area of either face of the coin in terms of pi (3.14)

254.34 mm².

Step-by-step explanation:

For this problem, we use the formula to find the area of a circle, which is . is the radius, which we can find by dividing the diameter by 2 and in this case is 3.14.

Therefore, the area of either face of the coin is 254.34 mm².

I hope this helps!

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
