Answer:
972π in³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = 
πr³ ← r is the radius
Here r = 9, thus
V = π × 9³ = π × 729 ( divide 3 and 729 by 3 )
= 4π × 243
= 972π in³
Answer:
<CBA
Step-by-step explanation:
<CBA = 90 degrees (given)
<ADB = 90 degrees (given)
Hence They are congruent, so choose A
Answer:
D
*thinking*
you would assume that it is 11 the actual is 10 19/24
Wich is not quite 11
