The circumference of a circle is given by the formula C=2πr. Find r if the circumference is 396 meters and π is 22/7.

larisa86 [58]

Answer:

r = 63 meters

Step-by-step explanation:

C=2πr

We know pi and C

396 = 2*22/7*r

396 = 44/7 *r

Multiply each side by 7/44 to isolate r

396*7/44 = 7/44 *44/7 *r

63 =r

Determine if the sequence is arithmetic. If it is, find the term named in the problem.

Brums [2.3K]

Answer:

$a_{39}$ <em>= 279</em>

Step-by-step explanation:

$a_{n}$ = $a_{1}$ + (n - 1)d

d = $a_{2}$ - $a_{1}$

~~~~~~~~~

d = - 17 + 25 = - 9 + 17 = - 1 + 9 = 8

$a_{39}$ = - 25 + 8(39 - 1) = 279

$a_{39}$ <em>= 279</em><em> </em>
