Describe in words the region of double-struck R3 represented by the equation: x2 + z2 ≤ 36.

Step-by-step explanation:

Given that:

if we assume that x is zero, then , i.e the radius of the circle goes from -6 to +6, Similarly, if we assume that z is zero, then , , . This implies that describes the circle with radius 6

is an equation at region which consist of those points whose distance  from the centre is at least with radius -6 and at most 6.

Therefore, the region is the solid cylinder of radius 6, where the Y axis is also the axis of the cylinder.

angle q= 92 degree

step-by-step explanation:

the solution is in the picture

when a quadrilateral is inscribed in a circle, the opposite angles are supplement to each other. in other words, the sum of the 2 angle is 180 degree
