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

Identify the sine function with the given attributes.
Thepotemich [5.8K]

Answer:

<em>Last option </em>

f(t)=sin(\pi(t -3)) + 4

Step-by-step explanation:

The general sine function has the following form  

y = Asin(bt-\phi) + k

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.  

\frac{2\pi}{b} is the period: time it takes the wave to complete a cycle.

k is the vertical displacement.

\phi phase shift

We know that:

amplitude: 1; period: 2; phase shift: 3; vertical shift: 4

Thus:

A =1

\frac{2\pi}{b}=2

b=\pi

\phi=3

k=4

Then the function is:

f(t)=sin(\pi(t -3)) + 4

The answer is last option
