The area of the circle is 113.04 cm²

<u>Step-by-step explanation:</u>

The given information are,

  • The diameter of the circle = 12 cm
  • The diameter must be converted into radius.

Radius = diameter / 2

Radius = 12/2 = 6 cm

Now, the formula for area of the circle is given by πr²

where,

  • r is the radius of the circle.
  • π has the default value 3.14

<u>To calculate the area of circle :</u>

Substitute r=6 and π=3.14,

Area of the circle = (3.14) × (6²)

⇒ 3.14 × 36

⇒ 113.04 cm²

The area of the circle is 113.04 cm²

Todd says that he can make 10 if he adds 32 coins to 28 coins. Is he correct? Explain how you know using words.
Andreas93 [3]
He was wrong, you cannot make 10 coins by adding 32 coins to 28 coins. If you want to obtain 10 coins from 32 coins and 28 coins, you can subtract 28 coins from 32 coins.
This can be illustrated as follows:
32-28=10

This is because you get the x from the square root (-6) and the y from the invisible 0. Because it doesn’t have a negative x, it goes up.

Elanso [62]

Answer: 0.0885

Step-by-step explanation:

Given : According to a recent Catalyst Census, 16% of executive officers were women with companies that have company headquarters in the Midwest.

i.e. p= 0.16

Sample size : n= 154

Now, the  probability that more than 20% of this sample is comprised of female employees is given by :-

P(p>0.20)=P(z>\dfrac{0.20-0.16}{\sqrt{\dfrac{0.16(1-0.16)}{154}}})

[∵ z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}]

=P(z>1.35)\approx1-P(z\leq1.35)=1-0.9115=0.0885  [Using the standard z-value table]

Hence, the required probability = 0.0885
