The circumference of the base of a cone is 24 inches. The slant height of the cone is 20 inches.

loris [4]

The surface area of a cone with circumference base of 24π inches and slant height of 20 inches is 384π inches² in terms of π.

<h3>Surface area of a cone</h3>

surface area = πr(r + l)

where

r = radius
l = slant height

Therefore,

l = 20 inches

24π = 2πr

r = 12

Therefore,

surface area = π(12)(12 + 20)

surface area = 12π(12 + 20)

surface area = 12π × 32

surface area = 384π inches²

Write the first four terms of the sequence defined by An=20-30(n-1)

monitta

The first four terms of sequence is 20, -10, -40, -70

Solution:

Given that we have to find the first four terms of sequence

Given recursive formula is:

$a_n = 20 - 30(n-1)$

To find the first term, substitute n = 1

$a_1 = 20-30(1-1)\\\\a_1 = 20-30(0)\\\\a_1 = 20$

Thus the first term of sequence is 20

To find the second term, substitute n = 2

$a_2 = 20-30(2-1)\\\\a_2 = 20-30(1)\\\\a_2 = 20-30\\\\a_2 = -10$

Thus the second term of sequence is -10

To find the third term, substitute n = 3

$a_3 = 20-30(3-1)\\\\a_3 = 20-30(2)\\\\a_3 = 20-60\\\\a_3 = -40$

Thus the third term of sequence is -40

To find the fourth term, substitute n = 4

$a_4 = 20-30(4-1)\\\\a_4 = 20-30(3)\\\\a_4 = 20-90\\\\a_4 = -70$

Thus the first four terms of sequence is 20, -10, -40, -70
