- In Exercises 44 and 45, use the formula from Exercise 43. Similar triangles were used to find h and H. A container of yogurt has the shape of a frustum of a cone. With the lower base having diameter length 6 cm and the upper base having diameter length 8 cm, the volume of such a container 7.5 cm tall can be determined by using H=30 cm and h=22.5 cm. Find its volume. A frustum of a cone is the portion of the cone bounded between the circular base and a plane parallel to the base. With dimensions are indicated, show that the volume of the frustum of the cone is V=13R2H13rh2arrow_forwardGiven: Isosceles RST RS=RT=17andST=16. Medians RZ, TX and SY meet at centroid Q. Find: RQandSQ Exercises 29, 30arrow_forwardGiven: ABC is isosceles with base AB AB=y+7BC=3y+5AC=9y Find: Whether ABC is also equilateral Exercises 25, 26arrow_forward

Hint: Find the value of xarrow_forwardIn Exercises 9 and 10, classify the triangle not shown by considering the measures of its angles. a In XYZ, mX=123. b In RST, mR=45, mS=65 and mT=70.arrow_forwardIn isosceles trapezoid WXYZ with bases ZY and WX, ZY = 8, YX = 10 and WX = 20. Find height h the length of ZD or YE. Exercises 19, 20arrow_forward
- The triangle that has vertices at M-4,0,N3,-1,andQ2,4 has been boxed in, as shown. Find the area of MNQ. Exercises 33, 34.arrow_forwardIn Exercises 15 to 20, use that fact that r2+h2=l2 in a right circular cone Theorem 9.3.6. Find the length of the radius r of a right circular cone in which h=6 yd and l=8 yd.arrow_forwardWhen the diagonals of rhombus MNPQ are drawn, how do the areas of the four resulting smaller triangles compare to each other and to the area of the given rhombus?

- In Exercises 34 and 35, give a paragraph proof for each claim. The volume V of a washer that has an inside radius of length r, an outside radius of length R, and an altitude of measure h is given by V=h(R+r)(Rr).arrow_forwardEach side of square RSTV has length 8. Point W lies on VR- and point Y lies on TS- in such a way to form parallelogram VWSY, which has an area of 16units2. Find the length of VW-.arrow_forwardGiven: ABC, whose sides are 13 in., 14 in., and 15 in. Find: a BD, the length of the altitude to the 14-in. side HINT: USE the Pythagorean Theorem twice. b The area of ABC, using the result from part a Exercises 39, 40arrow_forward
