Answer: 4.02 c
Step-by-step explanation:
so the area of a circle is equal to A=pi multiplied by the radius to the second power. And since that’s half a circle it would make sense for the area to be half of the full circle. The radius (half of the diameter and the area from the center of the circle to the outer edge.) is shown as 1.6ft, 1.6^2 is 2.56 and multiplied by pi that is 8.04 half of that is 4.02.
H=36in
d=30in
V=?
________
V=πR²h=π(
)²h=π*15²30=π225*30=6750π (~20250in³)
Answer: V of fish tank is 6750π in³ (~20250 in³)
Circle area = pi(r)^2
pi = 3.14
r = 5
5 * 5 = 25
25 * 3.14 = 78.5
Then, divide that in half because its a half circle.
10 * 4 = 40
40 + 39.25 = 79.25
79.25 in.
