We can't simplify it so that's the result :) I hope it will help you :)
Answer:
Step-by-step explanation:
38=2(5)+2(x ) find X
2x5-10

so you length is 7
Answer:
Step-by-step explanation:
slant height is given. Using Pythagorean theorem to find height.
h² = 10² - 5²
= 100 - 25
h² = 75
h = √75
h = 8.66 cm
Volume =(1/3)πr²h
= 226.62 cubic cm
