Find the area of the following circles. a. A circle with a 8-inch radius b. A circle with a 10-kilometer radius c. A circle with

Thepotemich [5.8K]

Area of a circle is $A= \pi r^2$ . The first one, a, the radius squared is 8*8=64. So $A=64 \pi$ . If you multiply in pi as 3.14, you'll have 200.96 square inches. The second one, b, the radius squared is 10*10=100. So $A=100 \pi$ square kilometers. If you multiply in pi as 3.14 you'll have 314 square kilometers. The third one, c, the radius squared is 14*14=196. So $A=196 \pi yd^2$ . Or you could multiply in pi as 3.14 to get 615.44 yd squared. For the last one, d, the radius squared is 22*22=484 cm. Therefore, $A=484 \pi cm^2$ , or multiply in 3.14 for pi to get 1519.76 cm squared. There you go!

Find an equation of the line that satisifes the given conditions. <br>Please help (30 points).

Ronch [10]

First, set up the equation using the point-slope formula (y-y1)=m(x-x1).
y1=-4 x1=-3 m=-7/2
(y+4)=-7/2(x+3)

Second, distribute -7/2.
(y+4)=(-7/2)x - 21/2

Third, subtract 4 from both sides.
(y+4)=(-7/2)x - 21/2
-4 -4
______________
y=(-7/2)x - 29/2

Over a 10 year period, there were a total of 246 unprovoked shark bites in Florida. Assuming that shark bites occur at the same

Serggg [28]

Answer: Our required probability is 0.067.

Step-by-step explanation:

Since we have given that

Number of days in a year = 365

Number of years = 10

So, Number of days in 10 years = 365 × 10 = 3650

Number of unprovoked shark bites in Florida = 246

so, Probability that there will be at least one unprovoked shark bite on a given day is given by

$\dfrac{246}{3650}\\\\=0.067$

Hence, our required probability is 0.067.
