Đoạn văn b ơi :33

a: Bán kính hình nón là:

(86-2,1*2)/2=40,9

Sxq=3,14*40,9*72=9246,672

S hình tròn=3,14*40,9^2=5252,6234

\(S_{vànhmũ+đáy}=3,14\cdot\left(\dfrac{86}{2}\right)^2=135.02\)

=>\(S_{vànhmũ}=5117.6034\)

\(S_{vải}=5117.6034+9246.672=14364.2754\)

b: Chiều cao hình nón là: \(\sqrt{72^2-40.9^2}\simeq59\)

\(V=\dfrac{1}{3}\cdot3.14\cdot40.9^2\cdot59=103301\left(cm^3\right)\)

do tam giác abc có b=90o

=> diện tích của tam giác abc là: 5x4=20cm2

vậy diên tích tam giác abc là 20cm2

\(Cl_2+H_2\rightarrow2HCl\)

\(Zn+2HCl\rightarrow ZnCl_2+H_2\)

\(ZnCl_2+Ba\left(OH\right)_2\rightarrow Zn\left(OH\right)_2+BaCl_2\)

\(Zn\left(OH\right)_2+2HCl\rightarrow ZnCl_2+2H_2O\)

Cl2+H2→2HClCl2+H2→2HCl

Zn+2HCl→ZnCl2+H2Zn+2HCl→ZnCl2+H2

ZnCl2+Ba(OH)2→Zn(OH)2+BaCl2ZnCl2+Ba(OH)2→Zn(OH)2+BaCl2

Zn(OH)2+2HCl→ZnCl2+2H2O

2:

a: AC=BC=6/2=3cm

b: Vì BD=BC

nên B là trung điểm của DC

c: AD=6+3=9cm

\(a,=\left(-\dfrac{1}{3}\right)^3=-\dfrac{1}{27}\\ b,=\left(-2\right)^6=2^6=64\\ c,=5^6:5^2=5^4=625\)

\(a,\left(-\dfrac{1}{3}\right)^2.\left(-\dfrac{1}{3}\right)=-\dfrac{1}{3}\)

\(b,\left(-2\right)^2.\left(-2\right)^4=\left(-2\right)^6\)

\(c,25^3:5^2=5^6:5^2=5^3\)
