The volume of a cone is 258.9 cubic centimeters. a cylinder has the same base and height as the cone. what is the volume in cubic centimeters of the cylinder

Answers

Answer 1
Answer:

Volume of a cylinder = A(base)*height

Volume of a cone = 1/3*A(base)*height

Because the base and height of the cylinder and cone are the same, we can write

Volume of the cone = 1/3*A(base)*height =1/3*Volume of the cylinder

Volume of the cone = 1/3*Volume of the cylinder, so

Volume of the cylinder=3*Volume of the cone =3*258.9=776.6 cm³

Volume of the cylinder= 776.6 cm³
Answer 2
Answer:

Answer:

776.7 cm^3

Eight less than a number doubled is twenty more than the number. What is the number?

Answers

Let the number be a ....=>Number doubled : 2a ..=>Eight less than the no. Doubled : 2a - 8=>Eight less than the no. doubled is 20 more than the no. : 2a - 8 = 20 + a=>2a - 8 - 20 - a = 0=>2a -a - 20 -8 = 0=>a -28 = 0=>a = 28=>so the number is 28...Hope it helps!!!

In a circle with a radius of 3 ft, an arc is intercepted by a central angle of 2π/3 radians. What is the length of the arc?

Answers

Answer:

Hence, the arc length is 2π feet or 6.28 feet.

Step-by-step explanation:

In a circle with a radius of 3 ft, an arc is intercepted by a central angle of 2π/3 radians.

If the central angle is measured in degrees than the arc length is given by:

arc length=(θ\360°)×2πr.

and if central angle is measured in radians than the arc length is given by:

arc length=θr. ( where r is the radius of the circle)

where θ is the central angle.

Hence, here we have:

r= 3 ft.

and θ=2π/3.

Hence the arc length is given by:

Arc length=(2π/3)×3=2π  feet.

Hence, the arc length is 2π feet or 2×3.14=6.28 feet.

Answer:

2 π

1.Simplifying the following expression small 1-3s-s+8-2, the new expression is blank

Answers

Answer:

Step-by-step explanation:

1 - 3s - s + 8 -2 = 1 + 8 - 2 -3s - s

                        = 9 - 2 - 4s

                         = 7 - 4s

Here, 1 , 8  & (-2) are like term and when we add we get 7

-3s & -s are like terms. Add the coefficient of s , -3 +(-1) = -4

Answer:

D: -2

Step-by-step explanation:

Let's time 2 on both sides.

Then the equation will be:

(3x+4)=x

3x+4=x

-x        -x

2x+4=0

-4       -4

2x=-4

x=-2

So the answer is D:-2.

Select the factors of x^2 -10x+25? A.(x+5)(x+5) B.(x-5)(x-5) C.(x+25)(x+1) D.(x-25)(x-1)

Answers

The correct answer is option B which is the factors are (x-5)(x-5).

What is a quadratic equation?

It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

The quadratic equation will be solved as follows:-

x² -10x + 25 = x² -5x - 5x + 25

                   =  x ( x- 5 ) - 5 ( x-5 )

                   =  ( x - 5 ) ( x - 5 )

The factors of the equation are 5 and 5.

Therefore the correct answer is option B which is the factors are (x-5)(x-5).
