Math 10 Assignment
Today's assignment: - Complete Exercises p. 42-44 #4-9, 11-19, 22
For #10 The slant height is calculated as square root of (height squared + half of the base squared)
So it would be written as the square root of (481 squared + 375.5 squared)
For #16 Look at the picture and calculate the value of the variable. For both pictures the variable is the slant height (s)
For 21 Read the question carefully. It says that the cone and the pyramid have the same surface area. You can use this information to calculate the slant height of the cone. Then with the slant height you can calculate the height of the cone like I showed in class.
Hi Mr.Arocena. I do not understand Question # 10. Is the base half of the height?
ReplyDeleteQuestion # 16: What do they mean by Calculate the dimension indicated by the variable?
Question # 21: In general I do not understand the question.
THANKS!!
