Find the area of the shaded region in terms of pi.

Step-by-step explanation:

Step-by-step explanation:

Let’s find the area of the circle.

A = 3.14(7)^2 = 153.86

Now the area of the square:

14•14=196

Now we find the area of the shaded region:

196 - 153.86 = 42.14

the shaded region is 42.14 cm

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'.
