Answer:

131.88 units

Step-by-step explanation:

Area of the circle = π $r^{2}$ = 1384.74 sq. units

$r^{2}$ = $\frac{1384.74}{3.14}$ = 441 = $21^{2}$

r = 21 units

Circumference of circle = 2πr = 2*3.14*21 = 131.88 units

Julia rounded to the nearest ten to estimate the difference between two numbers. The estimated difference was 10. What are four

serious [3.7K]

To round off to 10, the difference should range from 5 to 14. If the difference between two numbers is from 5 to 14, they all are rounded to 10.

Example:

$18-9=9$ (near to 10)

$26-15=11$

$46-39=7$

$50-42=8$
