Answer:

$50.40

Step-by-step explanation:

The garden has an area of ...

(15 ft)(12 ft) = 180 ft²

Amy wants to cover 1/4 of that with flowers, so the area devoted to flowers is ...

(1/4)(180 ft²) = 45 ft²

The cost for each square foot is $1.12, so the cost of the flowers will be ...

Answer:

394.67 minutes (or about 6.58 hours)

Step-by-step explanation:

<u>For 145.8 feet long fence:</u>

At a rate of 2.25 feet per minute, its gonna take him

$\frac{145.8}{2.25}=64.8$ minutes to pain

Also

At a rate of 0.75 feet per minute, its gonna take him

$\frac{145.8}{0.75}=194.4$ minutes to stain

<u>For 76.2 feet long fence:</u>

At a rate of 2.25 feet per minute, its going to take him

$\frac{76.2}{2.25}=33.87$ minutes to pain

At a rate of 0.75 feet per minute, its gonna take him

$\frac{76.2}{0.75}=101.6$ minutes to stain

In total, it's gonna take him:

64.8 + 194.4 + 33.87 + 101.6 = 394.67 minutes

In hours, that is 394.67/60 = 6.58 hours

Calculate the volume of a cone whose base radius is 3 and half cm and vertical height 24cm

Firlakuza [10]

The volume of a cone whose radius is 3 1 / 2 cm and vertical height is 24 cm is 307.72 cm³

<h3>Volume of a cone</h3>

The volume of a cone can be represented as follows:

volume = 1 / 3 πr²h

where

r = radius
h = height

Therefore,

r = 3 1 / 2 cm = 7 / 2 cm

h = 24 cm

Hence,

volume = 1 / 3 × π × (7 / 2 )² × 24

volume of a cone = 1 / 3 × π × 49 / 4 × 24

volume of the cone = 1 / 3 × π × 1176 / 4

volume of the cone = 1176 / 12 π

volume of the cone = 98π

volume of the cone = 307.72 cm³
