Another feature of the moons surface is long, narrow valleys called rillies. the hadley rille is 125 kilometers long, 0.4 kilometers deep and 1.5 kilometers wide at its widest point. express these distances in meters

Step-by-step explanation:

length = 125000

width = 1500

depth = 400

1 kl = 1000 meters

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
