Flashcards in Chapter 1 Practice Test Deck (20):
The given region is the combination of a semicircle with radius 6 cm and a square with side length 12 cm. Find the area of the given region using the formula for the area of a circle, A = πr^2 where r is the circle's radius, and the formula for the area of a square, A = s^2 where s is the length of a side of the square. Remember, a semicircle's area is one half the area of the circle with the same radius.
144 + 18π cm^2
The formula for the volume of a cone is V=1/3 Bh, where B is the area of the base. Use this formula to find the volume of the given cone.
Hint: The base of the cone is a circle and the formula for the area of a circle is A = πr2, where r is the circle's radius.
