Answer:

A =63.585 in^2

Step-by-step explanation:

The area of a circle is found by

A = pi r^2

A = pi (4.5)^2

A = pi(20.25)

We can approximate pi by 3.14

A = (3.14) (20.25)

A =63.585 in^2

Answer:

about 63.6 inches

Step-by-step explanation:

formula to find the area of a circle: pi*r^2

pi = 3.14

r = 4.5

3.14*4.5*4.5 = 63.585

Solve A=p+prt for r.

Furkat [3]

A = p + prt

The above equation can be solved for “r” in such a way.

Subtract “p” from both sides;

A – p = p + prt – p

A – p = prt

Divide both sides by “p” and “t”;

A/pt – p/pt = prt/pt

A/pt – 1/t = r

r = A/pt – 1/t
