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:
<h2>1525.7 square meters, approximately.</h2>Step-by-step explanation:
Notice that the radius is 28 meters, and the angle of the orange sector is 137°. However, the angle of the blue sector is:
360° - 137° = 223°
The area of a circular sector is
Replacing given values, we have
Therefore, the right answer is the second choice.
