One-third of a number t is less than or equal to 5
Kryger [21]

Answer:

t ≤ 15

Step-by-step explanation:

Hello!

To find the area of a circle you use the equation

\pi  r^{2}

r is radius which is half the diameter

r = 2.6 / 2

r = 1.3

Put in the values you know

\pi  1.3^{2}

Square the number

1.69 \pi  = 5.31

The answer is 1.69 \pi or ≈5.31

Hope this helps!
