Answer:

Correct choice is A.

Step-by-step explanation:

We have to find about which of the given choices is the formula for the volume of a pyramid with base area B and height h.

We know that formula of volume of pyramid is given by:

volume = \frac{1}{3}\left(Base\ area\right)\left(Height\right)

Plug the given values

volume = \frac{1}{3}\left(B\right)\left(h\right)

So the correct choice is A.

Answer: A.  \dfrac{1}{3}\times\text{B}\times\text{h}

Step-by-step explanation:

We know that the volume of a pyramid is given by :-

\text{Volume}=\dfrac{1}{3}\times\text{Base Area of the pyramid}\times\text{Height of pyramid}

Let B be the Base Area of the pyramid and h be the Height of pyramid, then the formula for the volume of a pyramid with base area B and height h will become :-

\text{Volume}=\dfrac{1}{3}\times\text{B}\times\text{h}

Hence, the formula for the volume of a pyramid with base area B and height h =\dfrac{1}{3}\times\text{B}\times\text{h}

The shorter leg of a right triangle is 21 feet less than the other leg. Find the length of the two legs if the hypotenuse is 39
mina [271]

Answer:

leg 1= 36  feet

leg2 = 15  feet

Step-by-step explanation:

Hi, we have to apply the Pythagorean Theorem:  

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (in this case the distance between Doreen’s house and the tower) and a and b are the other legs.  

leg1 = x

leg2 = x-21 (21 feet less than the other leg)

Replacing with the values given:  

39^2 = x^2 + (x-21)^2  

1,521 = x^2 + x^2 -42x +441

0 = 2x^2 -42x +441-1,521

0= 2x^2 -42x -1,080

For: ax2+ bx + c  

x =[ -b ± √b²-4ac] /2a  (quadratic formula)

Replacing with the values given:  

x=-(-42)± √(-42)²-4(2)-1080] /2(2)  

x= 42± √10,404] /4

x = 42± 102 /4

Positive:

x = 42+102 /4 = 36

leg 1= 36

leg2 = 36-21 =15

Feel free to ask for more if needed or if you did not understand something.

WITCHER [35]
Volume of a regular prism=height times area of base
area of base=5
height=1 and 1/2

volume=5 times 1 and 1/2
volume=5+5/2
