The area of the circle is 132.7 square centimeters. What is the diameter

1 answer:

7 0

Equating the formula (d is the diameter)

$\pi$ d^2/4 = 132.7
d^2 = 132.7*4/ $\pi$
d = $\sqrt{169.044586}$
d = 13.0017147331
d= 13cm

Answer:

-46

Step-by-step explanation:

We need to find the common difference of this arithmetic sequence:

$\frac{-26-(-10)}{10-6} =\frac{-16}{4} =-4$

So, the common difference d = -4. We can now write the equation:

$a_n=a_1+d(n-1)$

$a_{15}=a_6+d(15-6)=-10-4(9)=-10-36=-46$

So, the 15th term is -46.

Hope this helps!
