A cone has a radius of 6.2 mm and a height of 10.8 mm. What is the volume of the cone to the nearest tenth? use π = 3.14

guapka [62]

$\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the Concept of the volumes.

Here given as, r= 6.2 mm, h = 10.8 mm, π=3.14

hence, the volume of the cone is

Volume = 1/3(πr^2h)

===> vol = 1/3(3.14*(6.2)^2*(10.8))

==> Vol = 1/3*(1303.57)

==> Vol = 434.52 mm^3

Hence the volume of the cone is 434.52 mm^3

Kimmy bought a 5kg mg can of peanuts for $4.50 what is the unit price

Lina20 [59]

We know that the cost of 5 kg of peanuts is $4.50, then the unit price per kilogram is $4.50/5 kg = 0.90 $/kg And the unit price per gram is: $0.90 / kg * 1 kg/1000 = 0.0009 $/g or 0.09 cents/gram

A woman plans to buy some bottles of alcohol, a bottle of Heineken goes for $800 while that of monster drink $250. she doesn't h

Alja [10]

Answer:

The inequalities that must be satisfied is

$x + y \leq 32$

$x(800) + y(250) \leq 3500$

Step-by-step explanation:

Let the number of Heineken bottles be x

Let the number of monster drink bottles be y

Her crate cannot hold more than 32, This situation can be represented as

$\text{Number of Heineken bottles + number of monster drink bottles } \leq 32$

That is

$x + y \leq 32$ ------------------------(1)

Cost of one Heineken bottles = $800

Cost of one monster drink bottles = $250

then

$x \times \text{cost of one Heineken bottle } + y \times \text{ cost of one monster drink bottle} \leq 3500$ x

$x(800) + y(250) \leq 3500$ ------------------(2)

Roughly estimate the volume of a tennis ball in cubic cm by using 6 cm for diameter and 3 for pi. round the answer to the neares

galben [10]

The volume of ball is 113.04 cubic centimeter

Solution:

Given that we have to find the volume of tennis ball

Since the ball is of sphere shape, we can use the sphere formula

The volume of sphere is given by formula:

$V = \frac{4}{3} \times \pi \times r^3$

Where, "V" is the volume and "r" is the radius

Given that,

Diameter = 6 cm

Therefore,

$Radius = \frac{diameter}{2}\\\\Radius = \frac{6}{2}=3$

Substituting in formula, we get

$V = \frac{4}{3} \times 3.14 \times 3^3\\\\V = 4 \times 3.14 \times 3^2\\\\V = 12.56 \times 9\\\\V = 113.04$

Thus volume of ball is 113.04 cubic centimeter

Solve for the missing side in the special right triangle.

nevsk [136]

Answer:

Step-by-step explanation:

If I remember how to solve these questions correctly, if there is a triangle that is 45 degrees, the hypotenuse will be times the square root of 2 of the other two sides (which are equal to eachother). Hope this helped!
