This is the concept of algebra, to factor the expression we proceed as follows;
ab+4+a+4b
this can be written as:
ab+a+4+4b
factoring this we get:
a(b+1)+4(1+b)
=(a+4)(b+1)
the answer is (a+4)(b+1)

Volume of a sphere with a diameter of 8 meters? Use 3.14 for pi.

kvasek [131]

Answer: " 267.95 m³ " .
______________________________________________________
Explanation:
________________________________________________________

V = (4/3) * $\pi$ * r³ ;

Given: diameter, "d" = "8 m" ;

radius, "r" = 8 m / 2 = 4 m "

V = (4/3) * $\pi$ * r³

V = (4/3) * $\pi$ *(4m)³

V = (4/3) * (3.14) * 4³ * m³ ;

V = (4/3) * (3.14) * (4*4*4) * m³ ;

V = (4/3) * (3.14) * (64) * m³ ;

V = 267.9466666666666667 m³ ;

round to: " 267.95 m³ " .
