14) Dos triángulos son semejantes. Si los lados del triángulo más pequeño miden \( 3 \mathrm{~cm}, 4 \mathrm{~cm} \) y 5 cm , y el lado más largo del triángulo mayor mide 15 cm , ¿cuánto mide el lado más corto del triảngulo mayor? \( \begin{array}{llll}\text { a) } 3 \mathrm{~cm} & \text { b) } 9 \mathrm{~cm} & \text { c) } 12 \mathrm{~cm} & \text { d) } 6 \mathrm{~cm}\end{array} \)

Find the volume of the cone above. Select the formula for the volume of a pyramid \( \frac{1}{3} \cdot h \) Areaof Base \( \cdot h \) \( l \cdot w \cdot h \) \( 2 \cdot \pi \cdot r^{2} \cdot h \) Find the volume of the square based pyramid above.

Area and Circumference of a Circle Determine the area and circumference of a circle with radius 17 cm . Use the \( \pi \) button on your calculator and round your answers to the nearest hundrei Area \( =\square \) Select an answer \( \vee \) Circumference \( =\square \)

A rectangular field 225 ft by 120 ft has a ring of uniform with cut around the outside edge. The ring leaves \( 65 \% \) of the field uncut in the center. What is the width of the ring?

The volume of a cylinder with height \( h \) and radius \( r \) can be found using the formula \( V=\pi r^{2} h \). Sketch a cylinder with radius 9 feet and height 10 feet, then find the volume and select the correct units. Round your answer to the the nearest tenth. Volume \( =\square \)
