The circumference of a circle is 9π m. what is the area of the circle? asap! 4.5π m² 18π m² 20.25π m² 81π m²

20.25 m²

Step-by-step explanation:

the area (A) and circumference (C) of a circle are calculated using the formulae

C = 2πr and A = πr² ( where r is the radius )

calculate the radius using the formula for circumference

2πr = 9π ( divide both sides by 2π )

r = = = 4.5, hence

A = π × 4.5² = 20.25π m²

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

a: kite

step-by-step explanation:

figure lmno is located at l (1, 2) m (3, 2), n (3, 0), and o (0, −1). use coordinate geometry to best classify quadrilateral lmno.
