What is the volume of a cylinder that has a radius of 4 cm and a length of 8cm
Shkiper50 [21]

Answer:

volume of a cylinder = 401.92cm³

Step-by-step explanation:

to calculate the volume of a cylinder , we will use the formular for finding the volume of a cylinder

volume of a cylinder =  πr²h

given that

height of the cylinder = 8cm

radius of the cylinder = 4cm

volume of a cylinder = π × (4cm)² × 8cm

volume of a cylinder = π × 16cm² × 8cm

volume of a cylinder = π128cm³

value of π = 3.14

volume of a cylinder = 3.14 × 128cm³

volume of a cylinder = 401.92cm³

The width of a rectangle measures (2.5u+9.8)(2.5u+9.8) centimeters, and its length measures (1.5u+3.9)(1.5u+3.9) centimeters. Wh
icang [17]

Solution,

We have,

Width of rectangle, b = (2.5u+9.8) cm

Length of rectangle, l = (1.5u+3.9) cm

We need to find the expression for the perimeter of the rectangle. The formula for the perimeter of a rectangle is given by:

Perimeter = 2(l+b)

P = 2[(2.5u+9.8)+(1.5u+3.9)]

Collecting like terms

P = 2[(2.5u+1.5u)+(9.8+3.9)]

P=2(4u+13.7)

⇒ P = 8u+27.4

So, the expression for the perimeter of the rectangle is (8u+27.4) cm.
