Determine the height of a cone that has a diameter of 10 inches and a volume of 225 in^3

Mathematics

zhuklara [117]3 years ago

Answer:

h= 21.4859173174 in (about)

Step-by-step explanation:

This is a formula to determine the height of a cone: Given radius and volume calculate the height, slant height, lateral surface area and total surface area.

Given r, V find height

h = (3 * v) / (πr2)

h=3x225/π5(10/2=5, to find the radius)x2

h=675/π10

h=675/31.4159265359 (about)

therefore, h= 21.4859173174 in (about)

3b^2-4b+1=0 solve each equation with the quadratic formula
hjlf
First multiply 3 and the 1
Then simplify b^2-4b+3=0
Then divide both numbers by 3 (b-3/3)(b-1/3)=0
If it doesn’t go in even like the second term then bring it before the B
Then equal both terms to 0 and solve

1.3 x 0.4 x 2 = 1.04
0.5 x 0.4 = 0.2
(\frac{1}{2}(0.5 x 1.2)) x 2 = 0.6

1.04 + 0.2 + 0.6 = 1.84m²

Two sides of a right triangle have the lengths 4 and 5. What is the product of the possible lengths of the third side? Express t
marishachu [46]

Answer:

19.2

Step-by-step explanation:

<u>1st Case:</u>

4 and 5 are legs of the right triangle.

Using the pythagorean therom: a^2+b^2=c^2

We can say that 4^2+5^2=x^2

16+25=x^2

41=x^2

x=√41

√41 is about 6.4

x=6.4

<u>2nd Case</u>

5 is the hypotenuse of the right triangle and 4 is the legs.

Using the pythagorean therom: a^2+b^2=c^2

We can say that 4^2+x^2=5^2

16+x^2=25

x^2=9

x=3

<u>Final Step</u>

We need to multiply the two possible lengths for x. So for case 1 the length of x was 6.4 and for case two the length was 3. 6.4*3=19.2
