Answer:

98 pi inches ^2

Step-by-step explanation:

We know that the diameter is 28 inches

The radius is 1/2 diameter

r = 14 inches

Area of a circle is pi * r^2

A = pi r^2

= pi (14)^2

= 196 pi

A semi circle is 1/2 of a circle,so we take 1/2 the area

A semi circle = 1/2 A circle

= 1/2 (196 pi)

= 98 pi inches ^2

Write your own explicit formula. List the first 4 terms and solve for the 10th term using the formula. (show your work)

Shalnov [3]

Answer:

See below.

Step-by-step explanation:

Formula:

$a_n = 3(n + 4)$

First term: n = 1

$a_1 = 3(1 + 4) = 15$

Second term: n = 2

$a_2 = 3(2 + 4) = 18$

Third term: n = 3

$a_3 = 3(3 + 4) = 21$

Fourth term: n = 4

$a_4 = 3(4 + 4) = 24$

Tenth term: n = 10

$a_{10} = 3(10 + 4) = 42$
