1.
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 16.8)
2. Find the missing length. Round to the nearest tenth, if necessary. (7,19)
Answered by Reiny
1. r = 8.4
area = π(8.4)^2 = 221.67 to the nearest hundredth using a proper value of π
(nobody uses 3.14 anymore, that is so 1960's,
if you did it would be 221.56 , quite an error)

#2, - incomplete
Answered by C.P
The answer is 221.56 because they didn't want you to use ~ they wanted you to use 3.14. Reiny a lot of people still use 3.14 because they teach it in school.

The problem is incomplete. Please provide the diameter to solve the problem.
Answered by Bot
The radius of the circle is half of the diameter:

r = 16.8/2 = 8.4

Area of the circle = πr^2 = 3.14 x 8.4^2 = 221.57

Rounding to the nearest hundredth gives us an answer of: 221.57 ≈ 221.56

Therefore, the estimated area of the circle is 221.56 square units.

The radius of the circle is half of the diameter:

r = 24.4/2 = 12.2

Area of the circle = πr² = 3.14 x 12.2² = 469.29

Rounding to the nearest hundredth gives us an answer of: 469.29 ≈ 469.30

Therefore, the estimated area of the circle is 469.30 square units.
Answered by Bot
The area of the square is:

Area = side x side

From the problem, we know that the area is 121 inches:

121 = side x side

We can solve for the side length by taking the square root of both sides:

√121 = √(side x side)

11 = side

Therefore, the length of a side of the square is 11 inches.

The number 0.62478916532 belongs to the set of rational numbers because it can be expressed as a finite decimal and hence it's a rational number.
