What is the volume, in cubic cm, of a cylinder with a height of 8cm and a base radius of 7cm, to the nearest tenths place?
FromTheMoon [43]

Answer:

Volume of the cylinder =  1230.88\,cm^3

Step-by-step explanation:

Height(h) of the cylinder = 8 cm

Radius(r) of the base= 7cm

Volume of a cylinder is:

                  = \pi \times r^2\times h

As,

   \pi =\dfrac{22}{7} = 3.14

Putting the values in the formula:

Volume is:

           =3.14\times(7\times7)\times8\\\\=3.14\times49\times8\\\\=3.14\times392\\\\=1230.88\,cm^3

The volume of the cylinder is :  1230.88\,cm^3

1.
a^2+b^2=c^2
easy
a=a
b=13
c=21
a^2+13^2=21^2
a^2+169=441
minus 169 both sides
a^2=272
sqrt both sides
a=16.4924
D is answer



2. same thing
a=18
b=26
18^2+26^2=c^2
324+676=c^2
1000=c^2
sqrt both sides
31.6228=c
C is answer



3.
one way is to plug them in
remember that hypotonuse is longest side
A. 7^2+24^2=25^2, is that true?, yes it is treu
answer is A



4.
legs are 6 and 4
a=6
b=4
c=x
4^2+6^2=x^2
16+36=x^2
52=x^2
sqrt both sides
7.2111=x
7.2=x



5.c=20
a=x
b=14

x^2+14^2=20^2
x^2+196=400
minus 196 both sides
x^2=204
sqrt both sides
x=14.2829
x=14.3




1. D
2. C
3. A
4. 7.2
5. 14.3
