A Company Is Making Red Metal No Entry Signs With Outer Diameter Equal To 12 Inches. How Many Square

Answers

Answer 1

Answer:

62.8

Step-by-step explanation:

To find the area of metal required, we calculate the area of the outer circle and subtract the area of the two inner semicircles. The area of the outer circle is,

AOC=πr2=π(62)=113.0973 in2

The area of the inner semicircles is,

AIC=2⋅12πr2=π(42)=50.26548 in2

The total area of the sign is,

A=113.0973−50.26548=62.83182 in2

Rounded to one decimal place, the area of metal required is 62.8 square inches.

Answer 2

The area of metal required is 62.8 square inches.

What is the area of circle?

The area of a circle is the area covered by the circle in a two dimensional plane .

Area of the outer circle is,

=[tex]\pi[/tex]r²=[tex]\pi[/tex](6²)=113.04  square inches

The area of the inner semicircles is,

=[tex]\pi[/tex](4)²=50.24 square inches

The total area of the sign is,

=113.04−50.24=62.8 square inches

Hence, the area of metal required is 62.8 square inches.

P(A and B) = 1/10 x 1/4 = 1/40

From thea above information, we can see that the outcome of the event A cannot affect the outcome of the event B.

Therefore, the two events are independent.

A pair of shorts are £15 in a 40%. What was the non-sale price

Answers

Answer:

£10.71

Step-by-step explanation:

Given the original price including discount od shorts = £15

Percent discount = 40%

Original price = x

Using the expression to calculate x

x + (40%of x) = 15

x +0.4x = 15

1.4x = 15

x = 15/1.4

x = £10.71

Hence the non sale price is £10.71
