Area and percent . ​
siniylev [52]

Answer:

a. 61.92 in²

b. 21.396 ≈ 21.4%

c. $4.71

Step-by-step explanation:

a. Amount of waste = area of rectangular piece of stock - area of two identical circles cut out

Area of rectangular piece of stock = 24 in × 12 in = 288 in²

Area of the two circles = 2(πr²)

Use 3.14 as π

radius = ½*12 = 6

Area of two circles = 2(3.14*6²) = 226.08 in²

Amount of waste = 288 - 226.08 = 61.92 in²

b. % of the original stock wasted = amount of waste ÷ original stock × 100

= 61.92/288 × 100 = 6,162/288 = 21.396 ≈ 21.4%

c. 288 in² of the piece of stock costs $12.00,

Each cut-out circle of 113.04 in² (226.08/2) will cost = (12*113.04)/288

= 1,356.48/288 = $4.71.

the perimeter of football field in a rectangular form of a certain school is 296cm if the breath is2/3 of the length find the le
Pani-rosa [81]

Answer:

L = 29.6 cm

Step-by-step explanation:

Let Length be L and Breadth be B

<u><em>Condition 1:</em></u>

2(Length)+2(Breadth) = Perimeter

Where Perimeter = 296 cm

=> 2L + 2B = 296

=> 2(L+B) = 296

<em>Dividing both sides by 2</em>

=> L + B = 148   ------------------(1)

<u><em>Condition 2:</em></u>

=> B = \frac{2}{3} L  -------------------------(2)

Putting Equation 2 in 1

=> L + \frac{2}{3} L  = 148

Multiplying both sides by 3

=> 3L + 2L = 148

=> 5L = 148

=> L = 148/5

=> L = 29.6 cm
