Area of a circle = pi • radius^2

A = πr^2

Your circle's diameter is 3 inches, so the radius is 1.5 inches.

A = π • (1.5)^2

≈ 7.065

≈ 7.1

A ball is launched into the sky at 19.6 feet per second from a 58.8 meter tall building. The equation for the ball’s height, h,

zhenek [66]

Answer:

Therefore,

The ball strike the ground at time , t = 6 s

Step-by-step explanation:

Given:

The equation for the ball’s height, h, at time t seconds is

$h=-4.9t^{2}+19.6t+58.8$

To Find:

time, t = ? (When the ball strike the ground)

Solution:

When the ball strike the ground height, h will be ZERO,

So put h = 0 in above given equation for time,

$0=-4.9t^{2}+19.6t+58.8$

Which is a Quadratic Equation

Dividing throughout by - 4.9 we get

$0=t^{2}-4t-12$

On Factorizing, splitting the middle term we get

$t^{2}-6t+4t-12=0$

$t(t-6)+2(t-6)=0\\\\(t+2)(t-6)=0\\\\t=-2\ or\ t=6$

As time cannot be negative,

t = 6 s

Therefore,

The ball strike the ground at time , t = 6 s

Which ordered pair is the solution to the system of linear equations -5x+y=26 and 2x-7y=16

garri49 [273]

Use the elimination method.
(-5x + y = 26)7
2x - 7y = 16

-35x + 7y = 182
2x - 7y = 16

-33x = 198
x = -6

Substitiute -6 for x in one of the equations.
2x -7y = 16
2(-6) - 7y = 16
-12 - 7y =16
-7y = 28
y = -4

The ordered pair would be (-6,-4)
