Answer:

Step-by-step explanation

the figure is composed of a square with an isosceles right triangle inside, we find the area of the square and we take away the area of the triangle.

Triangle area = lxl, right-angled triangle area side by side divided by two.

square area

8 * 8 = 64cm²

Triangle area

6 * 6 : 2 = 18 cm²

Area of the shaded region

64 - 18 = 46 cm²

Answer: b, d

Step-by-step explanation:

Corresponding angles are formed when two parallel straight lines are cut by a transversal

$\angle b=62^{\circ}$

In the figure, $\angle d\ \text{and}\ 62^{\circ}$ are alternate angle

$\therefore \angle d=62^{\circ}$

Answer:

Option A

Step-by-step explanation:

Given:

Center of circle = (h,k)= (3,8)

Radius = r = 5

The standard form of equation of circle with center and radius is:

$(x-h)^2+(y-k)^2=r^2\\Putting\ the\ values\\(x-3)^2+(y-8)^2=(5)^2\\Simplifying\\x^2+9-6x+y^2+64-16y=25\\x^2+y^2-6x-16y+9+64=25\\x^2+y^2-6x-16y+73=25\\x^2+y^2-6x-16y+73-25=0\\x^2+y^2-6x-16y+48=0$

Therefore, the general form of the equation of circle given is:

$x^2+y^2-6x-16y+48=0$

Hence, option A is correct ..
