Answer:

a(85) = -1033

Step-by-step explanation:

Explicit Arithmetic Sequence:

an = a1 + d(n-1)

d = -12 (by -37 + 25)

a(85) = -25 + -12(85-1)

a(85) = -1033

To find the area of a circle with a diameter of 18.

Serga [27]

$\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the Concept of the areas.

Since we know that, radius = diameter /2

here, => d = 2r ,

hence we use the formula as,

A = πr^2 ,

here option d.) is correct.
