The volume of the cylinder is 254,571.43cm³.

The surface area of the cylinder is 22,628.57 cm².

<h3>What is the volume of the cylinder?</h3>

A cylinder is a three-dimensional object. It is a prism with a circular base.

Volume of a cylinder =πr²h

  • π = 22/7
  • r = radius = diameter / 2 = 60/2 = 30cm

22/7 x (30²) x 90 = 254,571.43cm³

Surface area = 2πrh + 2πr²

(2 x 22/7 x 30 x 90) + (2 x 22/7 x 30²)

16, 971.43 + 5657.14 = 22,628.57 cm²

What is the value of k if the line 5x+ky=12 passes through the point (2,-1).
olchik [2.2K]

Answer:

k = -2

Step-by-step explanation:

1. Substitute the point (2,-1) into the given equation 5x+ky=12. The first number is 2, the x-value. The second number is -1, the y-value.

5x + ky = 12

5(2) + k(-1) = 12

2. Simplify

5(2) + k(-1) = 12

10 + (-k) = 12

10 - k = 12

2. Isolate k

10 - k = 12

-k = 12-10

-k = 2   <= here multiply both sides by (-1)

k = -2
