Find the volume of the composite solid. Round your answer to the nearest tenth

Mathematics
1 answer:
Llana [10]3 years ago

Answer:

1131.0 m^3

Step-by-step explanation:

Let h1 represent the height of the top cone, and h2 the height of the bottom cone. The volume of a cone is given by the formula ...

V = (1/3)πr^2·h

so the volumes of both cones together will be ...

V = (1/3)πr^2·h1 + (1/3)πr^2·h2 = (1/3)πr^2·(h1 +h2)

= (1/3)π(6 m)^2(12 m + 18 m) = 360π m^3

≈ 1131.0 m^3

Answer:

f(2)=0. The third option is correct.

Step-by-step explanation:

Suppose we have a polynomial called f(x) and we know (x-2) is a factor of f. This means that we can express f(x) as:

f(x)=(x-2)\cdot g(x)

Being g(x) another unknown function.

Option 1: f(0)=(0-2)\cdot g(0)=-2\cdot g(0). Since we don't know the value of g(0), we cannot assure f(0)=-2. Incorrect

Option 2: f(-2)=(-2-2)\cdot g(-2)=-4\cdot g(-2). Since we don't know the value of g(-2), we cannot assure f(-2)=0. Incorrect

Option 3: f(2)=(2-2)\cdot g(2)=0\cdot g(0)=0. Regardless of the value of g(0), f(0) must be 0. Correct

Option 4: f(0)=(0-2)\cdot g(0)=-2\cdot g(0). Since we don't know the value of g(0), we cannot assure f(0)=2. Incorrect

If P(x) = 12x3 + 11x2 - 9x + 10 and<br> Q(x) = 4x2 – 3x + 2, find<br> P(x) + Q(x)
aniked [119]

Answer:

12x^3+15x^2-12x+12

Step-by-step explanation:

P(x) = 12x^3 + 11x^2 - 9x + 10

Q(x) = 4x^2 – 3x + 2

P(x) + Q(x) = 12x^3 + 11x^2 - 9x + 10+ 4x^2 – 3x + 2

Combine like terms

                 =12x^3+11x^2+4x^2-9x-3x+10+2

                  =12x^3+15x^2-12x+12

Joan incorrectly finds the volume of a cone with a radius of 4 cm and a height of 6 cm. She thinks the volume is 301.44 cm3. Her
Stolb23 [73]

Answer:

Correct volume = 100.48 cm³

Step-by-step explanation:

The formula for finding the volume of a cone is:

V = πr²(h/3)

r - Radius

h - Height

V - Volume

To find the correct volume of the cone, we just need to input the measurements into their respective places in the formula and solve. Your work should look similar to the following:

V = πr²(h/3)

V = π(4)²(6/3)

V = π(16)(6/3)

V = π(16)(2)

V = π(32)

V = 100.48 cm³

(You can use the work shown above to find Joan's mistake in her work.)

~Hope this Helps!~
