Answer:
732π cm^3
Step-by-step explanation:
Volume of the biggest cone
(15^2 * π *20)/3 = 1500π cm^3
Volume of the smallest cone
20^3 : 16^3= 1500π : x
x = (1500π * 4096)/8000= 768π cm^3
Volume of the frustum = 1500π - 768π = 732π cm^3

Answer:
12/sin90'=b/sin67'
12sin67'=bsin90'
b=12sin67/sin90'
Step-by-step explanation:
sister ,we can use the law of sines. since we have the angle of elevation and assume the wall makes a right angle with the ground, our angle opposite the ground is 180-[90+23=67

Answer:
35
Step-by-step explanation:
If is given the value -8 as it is the input then -->
