Use 3.14 for pie to estimate the area of a circle. The diameter is given. Round your answer to the nearest hundredth if necessary. (the diameter is 14.1)
2. Find the missing length. Round to the nearest hudredth, if necessary.
624.26
can i get all the answers
its 624.26
To estimate the area of a circle using the value of π as 3.14, you need to use the formula A = πr², where A represents the area of the circle and r represents the radius.
To find the radius given the diameter, you simply divide the diameter by 2. In this case, the diameter is given as 14.1, so the radius would be 14.1 / 2 = 7.05.
Now, plug the radius into the formula to find the estimated area:
A = 3.14 * (7.05)² = 3.14 * 49.7025 ≈ 155.73695.
Since the question asks to round the answer to the nearest hundredth, the estimated area of the circle would be approximately 155.74.
Regarding the missing length of 624.26, I'm afraid you haven't provided enough information or context for me to determine what length you are referring to. Can you please provide more information or rephrase the question?
LETS GOOOO
estimate the area of a circle.
A = pi * r^2
A = 3 * 7^2
A = 150 square units
(actual 3.14 * 49.7 = 156.07 square units)
Which missing length?
Remember that area of a circle = (pi)(r)(r)
and that the diamater = 2(r)
so since the diameter is 14.1 the radius is half of that or 7.05
Area = (pi)(r)(r)
= 3.14 x 7.05 x 7.05
=
