Area of small circle = PI x r^2
r = 1/2 the diameter ( 1/2 * 3 = 1.5)
3.14 x 1.5^2 = 7.065 square cm
there are 2 small circles so total area for them = 7.065 * 2 = 14.13 square cm
the area for the large circle = PI x r^2
the radius of the large circle is 3 cm
3.14 x 3^2 = 28.26 square cm
the area of the shaded area is: 28.26 - 14.13 = 14.13 square cm, which can round down to 14 square cm.
Answer:
a. $.04
Step-by-step explanation:
$1.79/48 = 0.037 = 0.04
Answer: $ 8.97
Step-by-step explanation:
Game =$9.78
toy=$ 6.34
sandwich =$4.91
Total amount spent=$9.78+$6.34+$4.91=> $21.03
Total amount=$30
left amount=total amount- amount spent
= $30-&21.03
=$8.97
Probability of 1st number being even : 3/7
probability of 2nd number being even : 2/6
probability of 3rd number being even : 1/5
probability of all 3 numbers being even : 3/7 * 2/6 * 1/5 = 6/210 = 1/35

Step-by-step explanation:
Step 1 : Trying to factor as a Difference of Squares : 1.1 Factoring: x2-3. Check : 3 is not a square !! Ruling : Binomial can not be factored as the difference of two perfect squares. ...
Step 2 : Solving a Single Variable Equation : 2.1 Solve : x2-3 = 0. Add 3 to both sides of the equation : x2 = 3.
