If f(x) has a leading term of 3x^4 and zeros at x=2, x=-2, and x= -5, choose all possibly true statements: 3-2 square root of 10 is a zero of f(x) The constant term is 4 x-5 is a factor of f(x) x^2- 4 is a factor of f(x) the sign of f(x) changes twice

1. to solve this problem, you must apply the formula for calculate the surface area of a cylinder, which is:     a=2πr²+2πrh    a is the surface area of the cylinder.  r is the radius of the cylinder.  h is the height of the cylinder.    2. let's call the smaller ganza "a" and the other one "b".    3. the surface area of the ganza "a" (aa) is:     aa=2πr²+2πrh    r=diameter/2  r=3.5 cm/2  r=1.75 cm    h=10 cm    4. when you substitute these values into the formula, you obtain:     aa=2πr²+2πrh  aa=2π(1.75 cm)²+2π(1.75 cm)(10 cm)  aa=41.125π cm²    aa=129.0 cm²      5. the surface area of "b (aa) is:     ab=2πr²+2πrh    r=5.5 cm/2  r=2.75 cm    h=24.5 cm    6. when you substitute these values into the formula, you obtain:     ab=2πr²+2πrh  ab=2π(2.75 cm)²+2π(2.75 cm)(24.5 cm)  ab=149.875π cm²  ab=471.0 cm²
