18.5% as a decimal is 0.185
0.186×3200= 592
3,200-592= $2,608

What is the volume of a hemisphere with a radius of 9.8 in, rounded to the nearest tenth of a cubic inch?

pogonyaev

Answer:

the volume of the hemisphere is 1970.2 cubic inches.

Step-by-step explanation:

The given is,

Radius of hemisphere is 9.8 inches.

Step:1

Formula of volume of hemisphere is,

..................(1)

Where,

r - Radius of hemisphere

Step:2

From the given,

r = 9.8 inches

Equation (1) becomes,

= (0.66666666)(3.1415)(942.192)

= 1971.23

Volume of hemisphere = 1971.23 cubic inches

Result:is 1970.2 cubic inches.

babymother [125]

Answer:

B 12.68

Step-by-step explanation:

you will need to find the distance between each segment-

so the length of DC, CF, FE, ED

$d=\sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2} }$

DC:

D(-2,-1) C(-1,2)

$d=\sqrt{(-1--2)^{2} +(2--1)^{2} } \\d=\sqrt{1^{2}+3^{2} } \\d=\sqrt{10} =3.16$

CF:

C(-1,2) F(1,1)

$d=\sqrt{(1--1)^{2} +(1-2)^{2} } \\d=\sqrt{2^{2}+-1^{2} } \\d=\sqrt{4+1} \\d=\sqrt{x} 5=2.24$

F(1,1) E(2,-2)

$d=\sqrt{(2-1)^{2} +(-2-1)^{2} } \\d=\sqrt{1^{2} +(-3)^{2} } \\d=\sqrt{1+9} \\d=\sqrt{10}= 3.16$

E(2,-2) D(-2,-1)

$d=\sqrt{(-2-2)^{2} +(-1--2)^{2} } \\d=\sqrt{(-4)^{2}+1^{2} } \\d=\sqrt{16+1} \\d=\sqrt{17}= 4.12\\$

3.16+2.24+3.16+4.12= 12.68

a cylinder and a cone start with the same radius and height the radius of the cone is then trippled and the height of the cone i

Fittoniya [83]

Answer:

Therefore the cone is the greatest relative increase in volume.

Step-by-step explanation:

Cone:

Original cone = (1/3)π(h)r^2

Changed cone = (1/3)π(h/2)(3r)^2

= (1/2)(1/3)π(h)9r^2

= (9/2) * Original cone

=4.5 * Original cone

Cylinder:

Original cylinder = π(h)r^2

Changed cylinder = π(2h)r^2

=2 * Original cylinder

Therefore the cone is the greatest relative increase in volume.
