Answer:
V= 904.896cm^3
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of a cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
h - 18cm
d - 8cm
d = 2 * radius
r = d/2
r = 8/2
r = 4cm
π - 3.142
Insert the values into the formula of volume of a cylinder
V = πr^2h
V = 3.142 * 4^2 * 18
= 3.142 * 16 * 18
= 904.896cm^3
Answer:
Volume of the prop = 706.5 in³
Step-by-step explanation:
Volume of the prop given in the picture = Volume of hemisphere + Volume of the cone
Volume of the hemisphere =
where 'r' = radius of the hemisphere
For r = 5 in,
Volume of the hemisphere =
= 261.67 in³
Volume of a cone =
Here r = radius of the circular base
h = height of the cone
For 'r' = 5 in and h 17 in.
Volume of the cone =
= 444.83 in³
Volume of the prop = 261.67 + 444.83
= 706.5 in³
We have to determine the number which is rounded to the nearest tenth in the expression 0.304 1.325.
So, let us divide 0.304 by 1.325.
So, we get = 0.229
Now, we have to round the number 0.229 to the nearest tenth.
The tenths place is to the right of the decimal. Now, we will consider the digit at hundredths place which is '2', which is less than 5.
Therefore, the number rounded to the nearest tenth is 0.2.
