C = 14π or in decimal rounded form 43.98

Step-by-step explanation:

Circumference of a circle formula: C = 2*π*r

Step 1: Since they give us the diameter, we need to find the radius

radius = diameter/2

radius = 14/2

radius = 7

Step 2: Find the circumference

C = 2*π*(7)

C = 14π

C = 43.98

C = 14π or in decimal rounded form 43.98

14π cm or 43.96 cm

Step-by-step explanation: To find the circumference of a circle, start with the formula for the circumference of a circle which is c = 2πr.

In this problem however, notice that we are given the diameter instead of the radius. To find the radius, remember that the radius of a circle is equal to half of the diameter so the radius of this circle will be equal to half of 14 centimeters or 7 centimeters.

Now to find the circumference, we plug 7 centimeters in for the radius in our formula and we have 2 π (7 cm) which simplifies to 14π cm.

So one way to write the circumference of the circle is 14π cm.

Now, remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.

So we have 14(3.14) cm which simplifies to 43.96 cm.

So another way to write the circumference of the circle is 43.96 cm.

Answer from: Quest

$a_1 = 1$ , and

$a_{n+1} = a_n + (n + 1)$ for $n \ge 1$

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote $a_1 = 1$ , $a_2 = 3$ , $a_3 = 6$ , so that we can call

1 the 1st term, 3 the 2nd term, 6 the 3rd term,etc.

note the following:

from the 1st term (1) to the 2nd term (3), we go up by 2,from the 2nd term (3) to the 3rd term (6), we go up by 3from the 3rd term (6) to the 4th term (10), we go up by 4, andfrom the 4th term (10) to the 5th term (15), we go up by 5.

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from $a_1 = 1$ , to get to $a_2 = 3$ , we add $2(=1+1)$

from $a_2 = 3$ , to get to $a_3 = 6$ , we add $3 (=2+1)$

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

$a_1 = 1$ , and $a_{n+1} = a_n +(n + 1)$ for $n \ge 1$
