Question

Find the mistake(s) in the problem below. Correct the mistake to find the correct area.
The radius of a circle is 53 mm.
r=53
53 divided by 2=26.5
d=26.5
A=3x26.5 squared
A=79.5
The area of the circle is 79.5

Answer 1

Answer:

Step-by-step explanation:

$A = \pi r^{2}$    we don't need d to solve for d, and also d is not radius divide by 2, d= 2r = 2(53) =106.

If pi = 3.14,

$A = \pi r^{2} \\A = 3.14(53)^{2}\\A = 8820.26$

If pi = 3

$A = \pi r^{2}\\A = 3(53)^{2}\\A = 8427$
