Lapatulllka [165]

Step-by-step explanation:

Using Pythagorus theorem:

$r = \sqrt{ {( - 6)}^{2} + {5}^{2} } = \sqrt{61}$

Therefore,

$diameter \: = 2 \sqrt{61} = 15.62$

A medical test has been designed to detect the presence of a certain disease. Among people who have the disease, the probability

Oksi-84 [34.3K]

Answer:

a) 0.497

b) 0.0047

Step-by-step explanation:

a) The probability that the person actually has the disease

$\frac{0.06 *0.93}{0.06 *0.93 + 0.06 *0.94} = 0.497$

b) The probability that the person actually does have the disease $\frac{0.06 *0.07}{0.06 *0.06 + 0.93 *0.94} = 0.0047$

A carpenter is creating a circular wooden table with a radius of 4 feet and needs to know the area of the table to purchase the

JulijaS [17]

Answer: The area of the circular wooden table = 50.24 ft²

Step-by-step explanation:

Given: The radius of the circular table = 4 feet

We know that area of a circle is given by :-

$\text{Area}=\pi r^2$

Therefore, the area of circular wooden table is given by :-

$\text{Area}=3.14(4)^2\\\Rightarrow\ 3.14\times16\\\Rightarrow\text{Area=}50.24\ ft^2$

The area of the circular wooden table = 50.24 ft²

QUICK<br><br> Find the area of the shaded region. Use 3.14 for pi.

ivolga24 [154]

Answer:

The shaded region is $353.25m^2$ .

Step-by-step explanation:

The area of a circle is defined by the multiplication of the square of its radius, or half its diameter, by pi, or simply $A=\pi r^2$ .

15m is the radius of the large circle, and also the diameter of the smaller circles.

The area of the shaded region will be the subtraction of the area of the two smaller circles from the area of the larger circle.

As such:

$A=\pi(15)^{2}-2(\pi(\frac{15}{2} )^{2})\\\\A=(3.14)(15)^{2}-2(3.14)(\frac{15}{2} )^{2}\\A=706.5-353.25\\A=353.25$
