Answer:
423 cm^2
Step-by-step explanation:
Area of a regular pentagon = Pa/2, where P = the perimeter and a = the apothem.
We can find the perimeter by
P = 5s where s is the side length since the pentagon is regular
P = 5( 14.1)
P = 70.5
A = P*a/2
= 70.5 ( 12)/2
=423 cm^2
Answer:
The third one, (x+5)^2 + (y+7)^2 = 74
Step-by-step explanation:
The equation for a circle is in the form (x-x coordinate)^2 + ( y - y coordinate )^2 = r^2
the radius is 5^2 + 7^2 = 25 + 49 = 74
and the center is (-5,-7), so it is + 5 and + 7
