X=12, because when you use the constant of proportionality, which in this case is three, that’s what you multiply by 4 in the numerator side to equal 12.
Answer:
B
Step-by-step explanation:
2.5 + (-1.5) = 1.0
2.5 - 1.5 = 1.0
Answer:
Radius of the sphere = r
<u>Volume of sphere:</u>
Radius of the hemisphere = 2r
<u>Volume of the hemisphere:</u>
- V₂ = 1/2×4/3×π(2r)³ = 1/2×8×4/3πr³ = 4V₁
The volume of the hemisphere is 4 times greater than the volume of the sphere
Answer:
56 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h(a + b)
where h is the perpendicular height and a, b the parallel bases
here h = 4, a = 5 + 9 + 5 = 19 and b = 9, thus
A =
× 4 × (19 + 9) = 2 × 28 = 56 cm²
