Question

What is the slant height of the pyramid to the nearest tenth?

A.) 13.9 mm

B.) 15.5 mm

C.) 12.5 mm

D.) 19.0 mm

Answer 1

check the picture below.

Answer 2

Answer:

(C) 12.5mm

Step-by-step explanation:

It is given that a pyramid having slant height AC is to be determined. From the given information, we get

AB=12mm, BC=3.5mm and we have to find out the value of AC.

Thus, using the Pythagoras theorem, we have

$(AC)^2=(AB)^2+(BC)^2$

Substituting the given values, we have

$(AC)^2=(12)^2+(3.5)^2$

$(AC)^2=144+12.25$

$(AC)^2=156.25$

$AC={\sqrt{156.25}}$

$AC=12.5mm$

Therefore, the value of the slant height is 12.5mm.

Hence, option C is correct.
