The volume of a cone is 480 pi cubic units and the height is 10 units. Find the radius of the cone.

Answers

Answer 1
Answer:

≈ 21.4 units

Step-by-step explanation:

Hi there !

Volume formula

V = πr²×h/3

3V = πr²

r² = 3V/π

r = √3V/π

replace

r = √3×480/3.14

= √1440/3.14

= √4586

≈ 21.4 units

Good luck !

r = -189

Step-by-step explanation:

-13 = r/9 + 8

-13 - 8 = r/9

Help me with (-6,-7);y=-4x+1

Answers

Answer: y=-4x-31

Step-by-step explanation:

To find a ling that is parallel to the given line and passes through the given point, we need to use the given point. We know that the slope MUST stay the same because parallel lines NEVER touch. All we have to do is plug in the point and find the y-intercept.

-7=-4(-6)+b            [multiply]

-7=24+b                 [subtract both sides by 24]

b=-31

Now, we know that y=-4x-31 is the equation.

Answer:

1) = 180 degree reason = being AB is a straight line or supplementary

2) = angle AOB reason = being all the angles are of a straight line AB

3) = x + 2x+34 + 20 = 180 degree. reason being supplementary angle

4) = 42 degree

1) fill 180° in the blank

Reason :

Because AOB angles is half a page so it equals 180°

What is -5n+7<57 and 6n+2<8

Answers

Answer:

if -5n+7<57, then n>-10.

if 6n+2<8, then n<1.

Step-by-step explanation:

-5n+7<57

1. subtract 7 from both sides:

-5n+7 -7< 57 -7

-5n<50

2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):

-5n ÷-5<50 ÷-5

n>-10

6n+2<8

1. subtract 2 from both sides:

6n+2 -2<8 -2

6n<6

2. divide both sides by 6:

6n ÷6<6 ÷6

n<1

factor the equation

Answers

Answer:

- (x - 4)(x - 11)

Step-by-step explanation:

Given

- x² + 15x - 44 ← factor out - 1 from each term

= - 1 (x² - 15x + 44) ← factor the quadratic

Consider the factors of the constant term (+ 44) which sum to give the coefficient of the x- term ( - 15)

The factors are - 4 and - 11 , since

- 4 × - 11 = + 44 and - 4 - 11 = - 15 , thus

x² - 15x + 44 = (x - 4)(x - 11) and

- x² + 15x - 44 = - (x - 4)(x - 11)
