Find the area of each circle and round to the nearest tenth.
radius= 3 and two thirds
To find the area of a circle, you can use the formula:
Area = π * (radius)^2
Given that the radius is 3 and two-thirds, we can convert it into a decimal by dividing the numerator (2) by the denominator (3):
3 and two-thirds = 3 + (2/3) = 3.6667 (rounded to four decimal places)
Now, we can substitute this value into the area formula:
Area = π * (3.6667)^2
Using the approximation for π as 3.14159, we can calculate the area:
Area ≈ 3.14159 * (3.6667)^2
≈ 3.14159 * 13.4407
≈ 42.2147
Rounding to the nearest tenth, the area of the circle is approximately 42.2 square units.
A = pi * r^2
A = 3.14 * 3.67777^2
A = 3.14 * 13.5255
A = 42.470
A = 42.5
