Height of a cone-shaped attic:
h = 18 ft,
d = 18 ft,
r = 18: 2 = 9 ft
V = r² π h / 3 =
= 9² π · 18 / 3 = 81 π · 6 = 486 π ft³
Answer:
The volume of the space in the attic is 486 π ft³.
Answer:
She need to make 98 on the last assignment.
Step-by-step explanation:
Average = 92
x = mark on last assignment
(88 + 97 + 91 + 86 + x) / 5 = 92
To solve for x...multiply 5 on each side
<em>(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5</em>
<em>This would get of / 5 so you don't need to divide by 5</em>
362 + x = 460
Subtract 362 from each side
x = 98
