Answer:
Radius of a circle= ![\sqrt[2]{17} m](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B17%7D%20m)
Step-by-step explanation:
As we know, area of a circle=π x 
So give area= 68π
= 68π=π x 
Simplify ( Cancel the similar signs)
=
= 68
= r =
=
= r = ![\sqrt[2]{17} m](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B17%7D%20m)
Hope it helps
Peace
And a brainliest would be really appreciated
Answer:
area of a semicircle is (pi * r^2)/2.
Step-by-step explanation:
Answer:
Step-by-step explanation:
5 consecutive multiples of 5....
x , x + 5, x + 10, x + 15, x + 20
the average is 20...
(x + x + 5 x + 10 + x + 15 + x + 20) / 5 = 20
(5x + 50) / 5 = 20
5x + 50 = 20 * 5
5x + 50 = 100
5x = 100 - 50
5x = 50
x = 50/5
x = 10......smallest number
x + 5 = 10 + 5 = 15
x + 10 = 10 + 10 = 20
x + 15 = 10 + 15 = 25
x + 20 = 10 + 20 = 30 <=== largest number
Answer:
h(t) = 4.68 seconds
Step-by-step explanation:
The function that represents the height of each firework in feet is :
.....(1)
We need to find the time the fireworks take to reach their maximum height. For maximum height,
dh/dt = 0
So,

Put t = 4.68 in equation (1).

So, the fireworks will take 4.68 seconds to their maximum height.

{is the same as / equal to:}

{Simplify the fraction to become:}
