Anunits, approximate the surface area of the sidewalls in terms of x. . Approximate the amouunt of material needed to manufacture the sidewalls if x =9 feet. TOPIARY Davea is planning to prune her landscaping bushes into topiaries shaped like cones. a. The radius of a bush is ix units and the slant height is 4x units. Approximate the lateral area of one topiary in terms of x and t. D. A frost is expected, and Davea is making plastic slipcovers to protect her new toplaries. Approximate the surface area of one slipcover to the nearest tenth If the slipcover does not cover the base of the topiary and x = 0.75 meter. Example 7 Find the surface area of each sphere to the nearest tenth. 19. 4.8 mm 17. 18. 32 m • 7 in 20. MOONS OF SATURN The planet Saturn has several moons, and they can be modeled accurately by spheres. Saturn's largest moon, Titan, has a radius of about 2575 kilometers.
