Answer:

a. Area of circle = 50.24 ft².

b. Circumference of circle = 25.12 ft.  

Step-by-step explanation:

Given the following data;

Diameter = 8ft

Pie, π = 3.14

Radius, r = diameter/2 = 8/2 = 4ft

a. To find the area of the circle;

Area of circle = πr²

Substituting into the equation, we have;

Area of circle = 3.14*(4)²

Area of circle = 3.14*16

<em>Area of circle = 50.24 ft²</em>

b. To find the circumference of the circle;

Circumference of a circle = 2πr

Substituting into the equation, we have;

Circumference of circle = 2*3.14*4

<em>Circumference of circle = 25.12 ft. </em>

Nuetrik [128]

Answer: v= 56 ft per second


Step-by-step explanation:

Given: A quarterback throws a football to a teammate.

Projectile motion formula is given by :-

h(t)=-16t^2+vt+h_0, where h_0=6.5

Now, to find  v at h=5 and t=3.5, substitute these values in the above equations, we get

5=-16(3.5)^2+v(3.5)+6.5\\\Rightarrow5=-16(12.25)+3.5v+6.5\\\Rightarrow5=-196+6.5+3.5v\\\Rightarrow\ 5=-189.5+3.5v\\\Rightarrow\ 3.5v=5+189.5\\\Rightarrow\ 3.5v=194.5\\\Rightarrow\ v=55.57142\approx56

Which is the equation of a line with a slope of -1/3 and a y-intercept at (0,1)?
Nutka1998 [239]

Answer:

The answer is

\huge \boxed{y =  -  \frac{1}{3}x + 1 }

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (0,1) and slope - 1/3

The equation is

y - 1 =  -  \frac{1}{3}(x - 0) \\ y - 1 =  -  \frac{1}{3} x

We have the final answer as

y =  -  \frac{1}{3} x + 1 \\

Hope this helps you
