Find total area of a regular pyramid with base of 2 and altitude of 3

2 answers:

6 0

I'll have to make some assumptions here. First, I'll assume that the length of one side of the base is 2 and that the altitude (height) is 3.

The area of the (square) base is 2^2=4. The area of ONE triangular side is
A=(1/2) b h; here that comes out to A = (1/2) (2) (3) = 3 square units.

The total area of the four sides is thus Atotal = 4(3 square units), or 12 square units. Add this to the area of the base (4) to obtain the total area of the prism: 12+4=16 square units.

You are not giving much information so the assumption is the base is 2 = meters and the height is 3 meters.<span>

An object at the top of a building with height 110 feet is thrown upward with an initial speed of 23 ft/s. Find its position z(t

alina1380 [7]

Answer:

Step-by-step explanation:

Given

Height of building is $h=110\ ft$

Initial upward velocity $u=23\ ft/s$

height of object is given by

$z(t)=ut+\frac{1}{2}gt^2$

but building is already at a height of 110 ft so z(t) must be given by

$Z(t)=ut+\frac{1}{2}(-g)t^2+110$

$Z(t)=23\times t-\frac{1}{2}\times 9.8\times t^2$

$Z(t)=-16t^2+23t+110$

Time when it hits is given by when Z(t)=0[/tex]

$-16t^2+23t+110=0$

$t=\frac{-23\pm \sqrt{(23)^2-4\times (-16)\times 110}}{2\times (-16)}$

$t=\frac{-23\pm 87}{-32}$

$t=3.43\ s$
