A solid oblique pyramid has a regular hexagon base with an area of 54_/3 cm^2 and an edge length of 6cm. Angle BAC measures 60 d

Lady_Fox [76]

Answer: The answer is (C) 324 cubic cm.

Step-by-step explanation: As given in the question, given a solid oblique pyramid with a regular hexagonal base and area 54√3 cm². Also, the edge length of the base is 6cm and ∠BAC = 60°.

We are to find the volume of the pyramid.

The formula for finding the volume of a pyramid is given by

$V=\dfrac{1}{3}b\times h,$

where, 'b' is the base area and 'h' is the perpendicular height of the pyramid.

Here, b = 54√3 cm², h = ?

Now, from the right-angled triangle ABC, we have

$\dfrac{\textup{BC}}{\textup{AC}}=\tan 60^\circ\\\\\Rightarrow \dfrac{h}{6}=\sqrt 3\\\\\Rightarrow h=6\sqrt 3.$

Therefore, the volume of the pyramid is

$V=\dfrac{1}{3}b\times h=\dfrac{1}{3}\times 54\sqrt 3\times 6\sqrt 3=324.$

Thus, the required volume is $V=324~\textup{cm}^3.$ This makes (C) as the correct option.

Two cats, Fluffy and Fireball, met in the park. Fluffy's tail is 1/3, of a meter long. Fireball's tail is 1/4 of a meter long.

Lunna [17]

1/3 - 1/4 = 4/12 - 3/12 = 1/12....Fluffy's tail is 1/12 meters longer then Fireball's tail

Type your number answer in decimal form. do not round . ? millimeters = 9.2 cenimeters

adell [148]

Answer:

10 centimeter=92 milimeter

Step-by-step explanation:

we know that

one centimeter contains 10 milimeter or

1 centimeter is equal to 10 milimeter

1 centimeter=10 milimeter

we have to find

how many milimetersare there in 9.2 milimeters

9.2 centimeter=? milimeter

for this we will multiply by 9.2 on both sides

1 centimeter=10 milimeter

9.2 centimeter=10*(9.2)=92 milimeter

10 centimeter=92 milimeter
