We know that
[volume of a cylinder]=pi*r²*h
so
[volume of the half cylinder]=pi*r²*h/2
r=10/2-----> r=5 in
h=12 in
[volume of the half cylinder]=pi*5²*12/2----> 150*pi in³
the answer is
150*pi in3
Answer: 90
Step-by-step explanation: Divide 20 by 4 and Multiply the 18
3/5= 3 fifth size strips
You want to find an equivalent fraction with the denominator of ten, correct? Then you would multiply the fraction in a way that will allow you to have a denominator of ten.
So...
3/5*2/2=6/10
You would need 6 tenth size strips.
Answer:
18, 54, 108
Step-by-step explanation:
Let the first angle is ‘x’
Second angle =3x
Third angle=2(3x)=6x
Sum of the three angles of a triangle =180 degrees
x+3x+6x=180
x=18
The first angle is 18,second angle is (3*18)=54.third angle is (6*18)=108
The angles are 18,54 and 108 degrees
