Step-by-step explanation:
Answer:
V=250.3cm³
Step-by-step explanation:
V=1/3 × π x 5.4² cm x 8.2cm
V= 1/3 x π x 5.4² cm x 8.2cm
V= 1/3 x π x 29.16 cm x 8.2cm
V=250.39cm³
V=250.3cm³

= radius
origin = ( 2 , -6 )
radius = 7
Answer:
a ≈ 5.3
Step-by-step explanation:
Using Pythagoras' theorem
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 6² = 8², that is
a² + 36 = 64 ( subtract 36 from both sides )
a² = 28 ( take the square root of both sides )
a = ≈ 5.3 ( to the nearest tenth )
