Answer:
4pi
Step-by-step explanation:
area of a circle is pi*r^2
and you have diameter of 4
so 4/2 gives radius which is 2
A = pi*2^2 = 4pi
The greatest common factor is 9.
Please take another picture i think i know the answer but i can’t see choices
P=2(L+W)
if length=7
and P=24
24=2(7+W)
divide both sdes by 2
12=7+W
minus 7both sides
5=W
width=5meters
<span>If the radius of a circle is doubled in length, the circumference of the circle is also doubled in length</span>
