Answer: 80 feet
Step-by-step explanation:
We can write these as fractions and do cross multiplication with the numerator being the height of the object while the denominator being the length of the shadow:
5 * 128 = 8x
640 = 8x
80 = x
Thus, the height of the lighthouse is 80 feet tall.
Answer:

Step-by-step explanation:
Volume of a cone=1540
, Radius=7cm.
The height of a cone=h
When we need to find the height of a cone, we can use the formula of the volume of a cone, which is
to find the height of a cone.

Put the pi value=22/7 and the value of radius which is 7 cm into the formula.


Move
to another side. 1540 divided by
to calculate what is the value of h, h is the height of a cone. Like this.


Rearrange the h.

Answer:
D 12.57
Step-by-step explanation:
diameter = 4inches hence radius = 2inches
if the crust covers the full pizza "around", technically its the circumfrence
hence 2πr
2×π×2= 12.566 ~ 12.57
