Answers

Answer 1

Answer: P% * X
P% * X
42.1% * 375.4
42.1%/100 = 0.421
0.421 * 375.4
So, your answer shall be:
158.0434

Answer 2

Answer: 1. Set up a proportion
x/375.5 = 42.1/100
2. Solve the proportion
x= 158.0434

$38.47

C.
$71.44

D.
$125.01

Answers

Use the formula for finding the area of a circle, then multiply it by each square meter.

A = π r²
A = π (3.5)²
A = 12.25π
A = 38.485

C = 3.25(38.485)
C = 125.01

Answer = $125.01

Area of circle = πr²

Radius, r = 3.5m,

Area = πr² = π*3.5*3.5 = 12.25π m²

Area ≈ 12.25 *3.141 ≈ 38.477 m²

Since the metal sells for $3.25 per square meter.

Total cost for 38.477 m² = 38.477 * 3.25 = 125.05

Answer is = $125.05

The answer is not really there, but let's say we can manage option D which is $125.01.
