Which equation can be used to find the surface area of the cylinder? A cylinder with a radius of 4 inches and height of 16 inche
elena-s [515]

Answer:

S = 2π(4)(16) + 2π(4²)

So option A is correct; S = 2 pi (4) squared + 2 pi (4) (16)

Step-by-step explanation:

The formula for total surface area of a cylinder is;

Total surface Area; S = 2πrh + 2πr²

Now,we are given;

Height;h =16 inches

Radius;r = 4 inches

Thus, plugging in the values into the Area formula, we have;

S = 2π(4)(16) + 2π(4²)

The correct answer from the options given is;

S = 2 pi (4) squared + 2 pi (4) (16)

What is the perimeter of abc
Ede4ka [16]

perimeter ≈ 18.9 units ( to 1 dec. place )

Calculate the lengths of the 3 sides using the distance formula

d = √( (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(1, 1) and (x₂, y₂ ) = B(9, 2 )

d = √( (9 - 1 )² + (2 - 1 )² ) = √(64 + 1 ) = √65

repeat with (x₁, y₁ ) = B(9, 2) and (x₂, y₂ ) = C(4,5 )

d = √( (4 - 9 )² + (5 - 2 )² ) = √(25 + 9 ) = √34

let (x₁, y₁ ) = A(1, 1 ) and (x₂, y₂ ) = C(4, 5 )

d = √( (4 - 1 )² + (5 - 1 )² ) = √(9 + 16 = √25 = 5

perimeter = √65 + √34 + 5 ≈ 18.9 units

If -1 is one of the zeroes of py 3x^3-5x^2-11x-3 find other zeroes
katrin2010 [14]

Given:

The function is:

y=3x^3-5x^2-11x-3

It is given that -1 is a zero of the given function.

To find:

The other zeroes of the given function.

Solution:

If c is a zero of a polynomial P(x), then (x-c) is a factor of the polynomial.

It is given that -1 is a zero of the given function. So, (x+1) is a factor of the given function.

We have,

y=3x^3-5x^2-11x-3

Split the middle terms in such a way so that we get (x+1) as a factor.

y=3x^3+3x^2-8x^2-8x-3x-3

y=3x^2(x+1)-8x(x+1)-3(x+1)

y=(x+1)(3x^2-8x-3)

Again splitting the middle term, we get

y=(x+1)(3x^2-9x+x-3)

y=(x+1)(3x(x-3)+1(x-3))

y=(x+1)(3x+1)(x-3)

For zeroes, y=0.

(x+1)(3x+1)(x-3)=0

(x+1)=0 and 3x+1=0 and x-3=0

x=-1 and x=-\dfrac{1}{3} and x=3

Therefore, the other two zeroes of the given function are -\dfrac{1}{3} and 3.
