What is the 72nd term of -27, -11, 5

FinnZ [79.3K]

Answer:

1109

Step-by-step explanation:

The first term is -27, and the common difference is 16.

The nth term is:

a = a₁ + d (n − 1)

a = -27 + 16 (n − 1)

a = -27 + 16n − 16

a = 16n − 43

The 72nd term is:

a = 16(72) − 43

a = 1109

The lateral area of a cone is 400 pi cm squared. The radius is 10 cm. Find the slant height to the nearest tenth.

Ilia_Sergeevich [38]

Answer:

Option A. $40\ cm$

Step-by-step explanation:

we know that

The lateral area of a cone is equal to

$LA=\pi rl$

we have

$LA=400\pi \ cm^{2}$

$r=10\ cm$

substitute and solve for l (slant height)

$400\pi=\pi (10)l$

simplify

$400=(10)l$

$l=400/10=40\ cm$
