10) V=πr² *h= π*10²*12≈3770
11) V=A(base)*h= (3√3/2)*(9²)*10=2104
A(base)=(P*a)/2=(6*9*3√3)/2=9*9*3√3/2
12)V=πr² *h=π*18² *6≈6107
13)V=4*3*12=144
14) h(triangle)=√(5²-3²)=√16=4
A(base)=(3*4)/2=6
V=A(base)* height (prism)=6*2=12
15) V=A(base)*h= (3√3/2)*(6²)*11= 1029
16)V=A(base)*h=2(1+√2)5²*22≈2656
The answer would be approximately 1.98
Answer:
1/5 . 950
This is cause 20% =20/100 and when reduced it is 1/5
Answer:
A
Step-by-step explanation:
5a+4=9a+3-4a
5a-9a+4a=3-4
a=-1
<span>x^2+6x+11=0
After solving this u will bet
X=-6+,-</span>√-8/2
So roots of a equation are imaginary
