Atoy manufacturer has designed a new piece for use in building models it is a cube with side length of 7mm and it has a 3mm diameter circular hole cut through the middle the manufacture wants 1,000,000 proto types how much plastic is used for each prototype?

a- 343mm^3
b- 145mm^3
c- 29.50mm^3
d-293.5mm^3

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'.
