A cylinder has a radius of 3 feet and a height of 7 feet. Which of the following can be used to calculate the volume of a cone t

kramer

Answer:

$(3.14)(3)(7)$

Step-by-step explanation:

we know that

The volume of the cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

we have that the radius and the height of the cone will be equal to the radius and the height of the cylinder

so

$r=3\ ft$

$h=7\ ft$

$\pi =3.14$

substitute the given values

$V=\frac{1}{3}(3.14)(3)^{2} (7)$

$V=\frac{1}{3}(3.14)(9)(7)$

Simplify

$V=(3.14)(3)(7)$

For each of the following, use logic laws to decide whether the statement is a tautology contradiction, or neither. a (a) (A B)

spayn [35]

Answer:

The statement $(A\rightarrow \lnot B)\land (B\rightarrow A)$ is a contingency.

The statement $(P\rightarrow \lnot P)\land P$ is a contradiction.

Step-by-step explanation:

A tautology is a proposition that is always true.

A contradiction is a proposition that is always false.

A contingency is a proposition that is neither a tautology nor a contradiction.

a) To classify the statement $(A\rightarrow \lnot B)\land (B\rightarrow A)$ , you need to use the logic laws as follows:

$(A\rightarrow \lnot B)\land (B\rightarrow A) \equiv$

$\equiv (\lnot A \lor\lnot B)\land(\lnot B \lor A)$ by the logical equivalence involving conditional statement.

$\equiv (\lnot B\lor \lnot A )\land(\lnot B \lor A)$ by the Commutative law.

$\equiv \lnot B \lor (\lnot A \land A)$ by Distributive law.

$\equiv \lnot B \lor (A \land \lnot A)$ by the Commutative law.

$\equiv \lnot B \lor F$ by the Negation law.

Therefore the statement $(A\rightarrow \lnot B)\land (B\rightarrow A)$ is a contingency.

b) To classify the statement $(P\rightarrow \lnot P)\land P$ , you need to use the logic laws as follows:

$(P\rightarrow \lnot P)\land P \equiv$

$\equiv (\lnot P \lor \lnot P)\land P$ by the logical equivalence involving conditional statement.

$\equiv P \land (\lnot P \lor \lnot P)$ by the Commutative law.

$\equiv (P \land \lnot P) \lor (P \land \lnot P)$ by Distributive law.

$\equiv F \lor F \equiv F$ by the Negation law.

Therefore the statement $(P\rightarrow \lnot P)\land P$ is a contradiction.

Math HW please help.

Margarita [4]

Answer:

A x = 3

Step-by-step explanation:

A = ½θR²

R = x

x = √(2Α/θ)

θ = (360 - 60)(π/180) = 5π/3 radians

x = √(2(15π/2) / (5π/3))

x = √(15π(3/5π))

x = √9

x = 3
