3) La medida del angulo \( P \) de un trianguio PRT es \( 60^{\circ} \) y las longitudes de los lados PR y PT son 12 y 15 respectivamente Calcula el area de la region PRT.

Similar polygons have corresponding angles that are \( \square \), and corresponding sides that are \( \square \).

What is the height of the cone with the radius \( =3 \mathrm{in} \). and volume of \( 50 \mathrm{in}^{3} \) ? Use 3.14 for \( \pi \).

of the wheel. (Take \( \pi=\frac{22}{7} \) ) The radius of a circle is 7 cm . Find the circumference of the circle. Hence, find th length of an arc of the circle which subtends an angle of 45 at the centre

Parabola

Similar polygons are two polygons with the same \( \square \) but not necessarily the same \( \square \).
