We know that
volume of a right circular cylinder=pi*r²*h
where
r ----> is the radius
h---> is the height
in this problem
r=6 cm
h=?
Volume=550 cm³
so
V=pi*r²*h------> h=V/[pi*r²]----> h=550/[3.14*6²]----> h=4.87 cm
<span>Round to the nearest tenth
</span>h=4.9 cm
the answer is
4.9 cm
17-34(304)$-5 this is what I put
Tan² B = 4
(tan B)² = 4
tan B = ±2
Basic Angle
= tan^-1 2
= 63.4° (1dp)
B = 63.4°, 116.6°, 243.2°, 296.6°
Assuming you're actually supposed to present your answers in 0dp, then all answers apply.
Answer : The two correct options are,
3.4a + 5.6b
5.6b + 3.4a
Step-by-step explanation :
The given expression is:
(-2.4a - 1.8b) - (-3.8a - 4.4b) + (2.0a + 3.0b)
First we have to open the brackets.
⇒ -2.4a - 1.8b + 3.8a + 4.4b +2.0a + 3.0b
Now keep like terms together.
⇒ -2.4a + 3.8a +2.0a + 3.0b - 1.8b + 4.4b
By subtraction or addition, we get:
⇒ 3.4a + 5.6b
or,
⇒ 5.6b + 3.4a
Hence, the expressions that equivalent to the given expression are, 3.4a + 5.6b and 5.6b + 3.4a
