Segment AB is a diameter of the sphere.
diameter = AB = 16 in.
radius = r = (16 in.)/2 = 8 in.
Volume of a sphere:
V = (4/3) * pi * r^3
V = (4/3) * (22/7) * (8 in.)^3
The water inside the bowl occupies half of the bowl, so the volume of the water is half the volume of the bowl.
Volume of water:
V = (1/2)(4/3)(22/7)(8^3) in.^3
Answer: Second choice.
To my calculations i think it’s c
4b^2 - 16 =
4(b^2 - 4) =
4(b + 2)(b - 2)
The answer is $24.41
Step 1. Calculate the area of the <span>circular piece of fabric.
Step 2. Multiply the area of the piece by the price of </span><span>$5.40 per ft² to get the total cost.
Step 1.
The area (A) of the circle with radius r is:
A = </span>π r²
π = 3.14
r = 1.2 ft
A = 3.14 * (1.2 ft)²
A = 3.14 * 1.44 ft²
A = 4.52 ft²
Step 2.
Make a proportion
1 ft² costs $5.40
4.52 ft² cost x
1 ft² : $5.40 = 4.52 ft² : x
x = 4.52 ft² * $5.40 / 1 ft²
x = $24.41
