The radius of the cone is 7 in and y = 25 in. What is the volume of the cone in terms of π? A cone with a right triangle formed

Lady bird [3.3K]

Answer:

142.1π in³

Step-by-step explanation:

Given that:

The radius (r) = 7 in

The slant height (y) = 25 in

Then the height (x) can be determined by using the Pythagoras rule:

y² = x² + r²

25² = x² + 7²

125 = x² + 49

125 - 49 = x²

x² = 76

x = √76

x = 8.7

The formula for the volume of a cone is;

= 1/3 πr²h

where;

height(h) is calculated as "x" from above = 8.7

Then;

= 1/3 × π × (7 in)² × 8.7 in

= 142.1π in³

Solve for x. (1 point) −3x + 2b > 8 x < the quantity negative 2 times b plus 8 all over negative 3 x > the quantity neg

masha68 [24]

Given:

$-3x+2b>8$

To find:

The value of x.

Solution:

We have,

$-3x+2b>8$

To find the value of x, we need to isolate x on one side.

Subtract 2b from both sides.

$-3x>8-2b$

Divide both sides by -3. On multiplying or dividing an inequality by a negative number, we need to change the sign of inequality.

$\dfrac{-3x}{-3}$

$x$

The required inequality for x is $x$ .

Therefore, the correct option is A.
