18. In the figure, o is the center of the circle passing through P, Q, R and S. If angle SOQ = 150°, find the values of x and y.

AveGali [126]

Answer:

x = 75°

y = 105°

Step-by-step explanation:

Angle subtended on the circumference of the circle is half of the angle subtended on the center of the circle.

$\therefore m\angle SRQ = \frac{1}{2} \times m\angle SOQ\\\\\therefore x = \frac{1}{2} \times 150\degree \\\\\red{\bold{\therefore x =75\degree}} \\$

Quadrilateral PQRS is a cyclic quadrilateral.

$\therefore m\angle R + m\angle P= 180\degree \\\\\therefore x + y = 180\degree \\\\\therefore 75\degree + y = 180\degree \\\\\therefore y = 180\degree - 75\degree \\\\\purple {\bold {\therefore y = 105\degree}} \\$

1 l Find the perimeter of a circle whose area is 154 cm?

Alenkasestr [34]

Answer:

44

Step-by-step explanation:

The formula to find to area of a circle is $\pi r^{2}$ = Area

The perimiter formula is $2\pi r$ = Perimeter

Since we know the area (154cm) we can find the radius (r) with the formula.

You first have to find what the radius of the circle is with.

$\pi =3.14$

$\pi r^{2}$ = 154

3.14 $r^{2}$ =154

Now simplify.

$r^{2}$ =49 (rounded)

r=7

Now we can find the perimeter with the formula above.

$2\pi r$ = P

Now plug in.

2(3.14)(7)= P

44=P (Rounded)
