The cone shown has a height of 5 inches and a

Slav-nsk [51]

Answer:

Therefore approximate Volume of Cone is 11.78 inch³.

Step-by-step explanation:

Given:

Cone Shape :

Height = h = 5 inches

Radius = r = 1.5 inches

To Find:

Volume of Cone = ?

Solution:

Formula for Volume of Cone is given by

$\textrm{Volume of Cone}=\dfrac{1}{3}\pi (Radius)^{2}\times Height$

Substituting the given values we get

$\textrm{Volume of Cone}=\dfrac{1}{3}\pi r^{2}\times h$

$\textrm{Volume of Cone}=\dfrac{1}{3}\times 3.14\times (1.5)^{2}\times 5=11.775\ inch^{3}$

Therefore approximate Volume of Cone is 11.78 inch³.

Solve 3^x−5 = 9. (3 points) Select one: a. x = −3 b. x = 2 c. x = 7 d. x = 8

goldfiish [28.3K]

ANSWER

C. x=7

EXPLANATION

The given exponential equation is

${3}^{x - 5} = 9$

We rewrite the right hand side as 3 raised to exponent 2.

${3}^{x - 5} = {3}^{2}$

Observe that the base of both sides of the equation are equal.

We now equate the exponents.

$x - 5 = 2$

Solve for x,

$x = 2 + 5$

$x = 7$

The correct choice is C.
