The radius of the base of a cone is 6 inches the height of the cone is 6 inches. Which is closest to the volume of the cone

Answers

Answer:

V = 226.19

Step-by-step explanation:

v=(Pi)(r^2)(h/3) = 3.14(6^2)(6/3) = 3.1415(36)(2) = 226.19

The closest to the volume of the cone is given by 226.19.

We have given that,

The radius of the base of a cone is 6 inches the height of the cone is 6 inches.

What is the formula of the volume cone?

V=(Pi)(r^2)(h/3)

V= 3.14(6^2)(6/3)

V= 3.1415(36)(2)

V= 226.19

Answer:

m∠ONP = 43*

m∠LNO = 137*

m∠MNP = 137*

Step-by-step explanation:

Each line segment is a straight line meaning they are each worth 180°, so if you take 43° from 180° you're eft with 137° which is what ∠LNO and ∠MNP are equal to. ∠ONP is 43° since it is a vertical angle to ∠MNL which is also 43°.

5. 3(x - 1) = 23 – 5(x + 2)​

Answers

Answer:

x = 2

Step-by-step explanation:

3(x - 1) = 23 - 5(x + 2) ← distribute parenthesis on both sides

3x - 3 = 23 - 5x - 10

3x - 3 = 13 - 5x ( add 5x to both sides )

8x - 3 = 13 ( add 3 to both sides )

8x = 16 ( divide both sides by 8 )
