What is the exact volume of a cylinder whose radius is 13 meters and whose height is 20 meters? Enter your answer, in terms of π
ddd [48]
Hello!

The equation to find the volume of a cylinder is

V =  \pi  r^{2} h

V is volume
r is radius
h is height

Put in the values you know

V =  \pi  13^{2} * 20

Square the number

V =  \pi 169 * 20

Multiply

V = 3380 \pi

The answer is 3380 \pi

Hope this helps!

3x^2-x=10<br><br> Find factors <br><br><br> Determine zeros
Sophie [7]

Factors are (3x + 5) and (x - 2). Zeros are -5/3 and 2.

Step-by-step explanation:

  • Step 1: Given quadratic equation 3x² - x = 10 ⇒ 3x² - x - 10 = 0
  • Step 2: Use factoring method (product and sum rule) to find factors and zeros. So the equation can be written as below.

⇒ 3x² - 6x + 5x - 10 = 0

⇒ 3x(x - 2) + 5(x - 2) = 0

⇒ (3x + 5)(x - 2) = 0 These are the factors of the equation.

  • Step 3: Find zeros by equating the factors to 0.

⇒ 3x + 5 = 0 and x - 2 = 0

⇒ x = -5/3 and 2
