A cylinder has a radius of 8 meters and a height of 4 meters. .
Novay_Z [31]
<h2><u>Solution</u> :-</h2>

Given : Radius of cylinder = 8 m

Height = 4 m

Volume of cylinder = πr²h cu. units

= 22/7 × 8 × 8 × 4 m³

= 804.57 m³ (approx.)

Curved surface area = 2πrh sq. units

= 2 × 22/7 × 8 × 4 m²

= 201.14 m² (approx.)

Total surface area = 2πr(r + h) sq. units

= 2 × 22/7 × 8 (8 + 4) m²

= 2 × 22/7 × 8 × 12 m²

= 603.43 (approx.)

Simplify, write your answer in scientific notation<br> (4 x 10-6) + (3 x 10-3)
slavikrds [6]

Answer:

Step-by-step explanation: 3004 x 10⁻⁶

These numbers were written in standard forms or in scientific notation or in compressed manner

4 x 10⁻⁶ = 0.000004

3 x 10⁻₃ = 0.003

Adding the two together  gives

0.000004 + 0.003 = 0.003004

                               = 3004 x 10⁻⁶
