Find the are of the given circle round to the nearest tenth 3.5cm
Is that 3.5 whatevers the diameter? radius ? circumference?
To find the area of a circle, you can use the formula:
Area = π * r^2
where π (pi) is approximately 3.14159, and r is the radius of the circle.
Given that the radius of the circle is 3.5 cm, we can substitute this value into the formula:
Area = 3.14159 * (3.5 cm)^2
Calculating the expression inside the parentheses first:
Area = 3.14159 * 12.25 cm^2
Now, multiply the two numbers:
Area ≈ 38.484 cm^2
Therefore, the area of the circle is approximately 38.5 square centimeters (rounded to the nearest tenth).
To find the area of a circle, you can use the formula:
Area = π * radius^2
Given that the radius is 3.5 cm, we can substitute this value into the formula to calculate the area.
Area = π * (3.5 cm)^2
To get the value of π, we can use an approximation of 3.14159.
Area ≈ 3.14159 * (3.5 cm)^2
Calculating the equation:
Area ≈ 3.14159 * (3.5 cm)^2
≈ 3.14159 * 12.25 cm^2
≈ 38.485 cm^2
Therefore, the area of the circle is approximately 38.485 square centimeters. Rounding to the nearest tenth, the area would be 38.5 square centimeters.
