Answer:
you can answer it like 15 to 3 or
15:3
Diameter(d)=8 in.
radius(r)= d/2= 4 in.
height(h)= 3r = 3(4) = 12 in.
Volume=
<u /><em>
r </em>²
<em>h
=</em>(3.14)(4)²(12)
=(3.14)(16)(12)
=602.88 in.
Therefore, the volume of the cylinder is 602.88 in.
5 and 8
Step-by-step explanation:
area= base x altura= 5x8=40
perimetro= base+base+altura+altura = 5+5+8+8=26
30.78cm 32.36cm 73.14cm the process is shown in the following picture
Answer: 7a^2+2a+7
Step-by-step explanation:Distribute the Negative Sign:
=9a2+7a+8+−1(2a2+5a+1)
=9a2+7a+8+−1(2a2)+−1(5a)+(−1)(1)
=9a2+7a+8+−2a2+−5a+−1
Combine Like Terms:
=9a2+7a+8+−2a2+−5a+−1
=(9a2+−2a2)+(7a+−5a)+(8+−1)
=7a2+2a+7
