5.8x10^-1 - 7.4x10^0 in scientific notation.

Whitepunk [10]

5.8 × 10⁻¹ = 0.58

7.4 × 10⁰ = 7.4

0.58 - 7.4 = -6.82

(5.8 × 10⁻¹) - (7.4 × 10⁰) = -6.82 × 10⁰

A silo is a composite of a cylindrical tower with a cone for a roof. Find the volume of the silo if the radius of the base is 12

goblinko [34]

Answer: C. 5,127,079 ft^3

Step-by-step explanation:

Given : A silo is a composite of a cylindrical tower with a cone for a roof.

Base radius : r = 120 feet

Height of roof ( cone ) h = 25 feet

Total height of silo = 130 feet

Then , height of cylindrical part H= 130 - 25 = 105 feet

Volume of silo = volume of cylinder +volume of cone

$=\pi r^2H+\dfrac{1}{3}\pi r^2h$

$=\pi r^2(H+\dfrac{h}{3})$

Substitute corresponding values

$=(3.14159265359)(120)^2(105+\dfrac{25}{3})\\\\=(3.14159265359)(14400)(\dfrac{340}{3})\\\\=5127079.21066\approx5127079\ ft^3$

Hence, the correct answer is C. $5,127,079\ ft^3$ .
