remember that to put a number in scientific notation is necessary to have the first digit of the number different to 0, so
to calculate the order of magnitude, if the number is greater than 3.16, we assume it as a 10, so in this case as 7.654 > 3.16 we get that the order is
So the order is 10^-3
The area of circle is 2463.0086 cm².
Step-by-step explanation:
Given,
Diameter of circle = 56 cm
Radius of circle =
Radius of circle =
We know that;
Area of circle =
Area of circle =
Area of circle = π * 784
Area of circle = 2463.00864041 cm²
Rounding off to four decimal places
Area of circle = 2463.0086 cm²
The area of circle is 2463.0086 cm².
