Assuming that is a square pyramid

that is the square base+4 triangles
that is
side^2+4(1/2bh)
where b=side=14in
and h=height=13in

surface area=14^2+4(1/2)(14)(13)
SA=196+(2)(182)
SA=196+364
SA=560 square inches

Answer:

105

Step-by-step explanation:

$A=lw$ $A=$ (.5)πr²

to get the area of the shaded parts you have to subtract the area of the semicircle from the area of the rectangle

$A=(16)(9)$

$A=144$

$A=\frac{(3.14)(5)^2}{2}$ $A=\frac{(3.14)(25)}{2}$ $A=\frac{78.5}{2}$

$A=39.25$

subtract the areas

$144-39.25=104.75$

$104.75$ ≅ $105$

Could anyone help me with this problem i'm stuck <br><br> h(17)= ?

nikdorinn [45]

Answer:

$\sqrt{17t}$

Step-by-step explanation:

Consider the right side of the table

It informs us of the values for h(t) for different values of t

The top one informs us what h(t) is when t = 17, that is

h(t) = $\sqrt{17t}$ , when t = 17, thus

h(17) = $\sqrt{17t}$
