Answer:
134.04 cm³ (rounded to tenths)
Step-by-step explanation:
The radius(r) is 4 cm
The height(h) is 8 cm
Using the equation and plugging in the values, you get

Answer:
y ≈ 2.5
Step-by-step explanation:
Using the Sine rule in Δ XYZ
=
, substitute values
=
( cross- multiply )
y sin50° = 2 sin75° ( divide both sides by sin50° )
y =
≈ 2.5 ( to the nearest tenth )
Answer:
10
Step-by-step explanation:
f(x) =3x-x=2x,
f(7-2)=f(5)= 2*5=10
5^4 * 5^(-6) * 5
= 5^4 * 5^(-6) * 5^1
= 5^[ 4 + (-6) + 1 ]
= 5^[ 4 - 6 + 1 ]
= 5^(-1) <----- this is the answer.
I hope this helps. =)
