Answer/Step-by-step explanation:
Volume of a sphere = ⁴/3πr³
1. r = ½ of 14.4 = 7.2 in.
Volume = ⁴/3 × π × 7.2³ = 1563.46 ≈ 1563.5 in.³
2. r = 6 yd
Volume = ⁴/3 × π × 6³ = 904.78 ≈ 904.8 yd³
3. r = 8 mm
Volume = ⁴/3 × π × 8³ = 2144.66 ≈ 2144.7 mm³
4. r = ½ of 13.5 = 6.75 cm
Volume = ⁴/3 × π × 6.75³ = 1288.25 ≈ 1288.3 cm³
5. r = 4.7 in.
Volume = ⁴/3 × π × 4.7³ = 434.89 ≈ 434.9 in.³ (nearest tenth)
Answer:
PR = PQ and ST = UT.
If this is not correct then:
PR = 8 ans UT = 2z+3
Step-by-step explanation:
The slope of the line is
(9-5) / (4- -2) = 4/6 = 2/3 .
If the x-intercept is -2 and the y-intercept is 1, then the equation of the line is
y = 1/2 x + 1 .
None of the choices is correct.
