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?
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

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
=
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
=
its 624.26
