Find the volume of a solid enclosed by the paraboloid z = x2 +y2 and a plane z = 9

The plane lies above the paraboloid , so the volume of the bounded region is given by

Convert to cylindrical coordinates, setting

and the integral is equivalent to

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'.

you never say the total so we cant find the percentage used for petrol
