A 3 inch radius circle is drawn inside a 7 inch radius circle. If you throw a dart at these circles, what is the probability you
lorasvet [3.4K]

Answer:

Step-by-step explanation:

The first step is to determine the areas of the inner and the bigger circles.

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Considering the inner circle,

diameter = 148.4 cm

Radius = 3 inches

Area = 3.14 × 3² = 28.26 inches²

Considering the bigger circle,

Radius = 7 inches

Area = 3.14 × 7² = 153.86 inches²

The area between the bigger and inner circles is

153.86 - 28.26 = 125.6 inches²

Probability = number of favourable outcome/number of total outcome.

the probability you land inside the bigger circle but outside smaller circle is

125.6/153.86 = 0.82

How do I answer this?
12345 [234]

Answer:

Step-by-step explanation:

area of trapezium ABCD

=(16.5+12)/2 \times 15

=(28.5)/2 \times 15

=213.75 cm^2

\frac{PQ}{DC} =\frac{8}{12} =\frac{2}{3}

Area of PQRS

=213.75 \times (\frac{2}{3} )^2\\=213.75 \times\frac{4}{9} \\=95 ~cm^2

area of green portion=213.75-95=118.75 cm²

What is the value of this expression? 40 ÷ [24 – 4 x (2 + 3)]
Lady bird [3.3K]

Answer:

The value of this expression is 10.

Step-by-step explanation:

Follow the PEMDAS order of operations

40 ÷ [24 – 4 x (2 + 3)]

Calculate within the parentheses

= 24 - 4 x (2+3)

= 24 - 4 x 5

= 24 - 20

= 4

= 40 ÷ 4

Multiply and Divide

= 10
