Find the volume of a cone with a height of 3.25 centimeters and a diameter of 2.2 centimeters.

saveliy_v [14]

Answer:

As per Provided Information

Height of cone h is 3.25 cm

Diameter of cone is 2.2 cm

Radius = Diameter/2

Radius = 2.2/2

Radius = 1.1 cm

We have been asked to determine the volume of the cone .

Using Formulae 

$\boxed{\bf \:Volume_{(Cone)} = \cfrac{1}{3} \pi {r}^{2}h}$

Substituting the given value and let's solve it

$\sf\longrightarrow \: Volume_{(Cone)} = \cfrac{1}{3} \times 3.14 \times {1.1}^{2} \times 3.25 \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = \cfrac{1}{3} \times 3.14 \times 1.21 \times 3.25 \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = \cfrac{1}{3} \times 3.14 \times 3.9325 \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = \cfrac{1}{3} \times 12.34805 \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = \cfrac{12.34805}{3} \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = 4.11 {cm}^{3}$

Therefore,

Volume of the cone is 4.11 cm³ .

What is the volume of a sphere with a radius, r = 0.5?

sattari [20]

Answer:

V = 0.52 cm³

Step-by-step explanation:

radius r = 0.5 cm

volume V = 0.523333333 cm³

surface area A = 3.14 cm²

circumference C = 3.14 cm

In Terms of Pi π

volume V = 0.166666667 π cm³

surface area A = 1 π cm2

circumference C = 1 π cm

Agenda: r = radius

V = volume

A = surface area

C = circumference

π = pi = 3.1415926535898

Formulas:

Sphere Formulas in terms of radius r:

Volume of a sphere:

V = (4/3)πr³

Circumference of a sphere:

C = 2πr

Surface area of a sphere:

A = 4πr²

5x+8y=6p Solve for y

MariettaO [177]

5x + 8y = 6p Subtract 5x from both sides
8y = 6p - 5x Divide both sides by 8
y = $\frac{6}{8}$ p - $\frac{5}{8}$ x

jesse drives to work. The distance jesse's car travles (d) on a number of gallons of gas (g) is given y the equation d=15g.

Mademuasel [1]

You need to know what the distance jesse traveled is and then the number of gallons of gas she has then you plug it it.

distance equals 15 times the amount of gas in gallons
d=15g
