1 Use a calculator to find the volume of a sphere when the radius is 6. (V = 4 3 πr 3 ) A telescope is supported by a tower that casts a shadow 40 meters long. The distance from the top of the tower to the end of the shadow is 50 meters. How high is the tower? Use a calculator to find the missing sides of these right triangles. If a giraffe stands 576 cm tall, how long a shadow would it cast if it is compared to a man who is 180 cm tall casting a shadow 1 m long?
