The lateral area is π r ℓ units²
<span>The base is 20 feet across so the radius is 10 feet </span>
<span>Multiply 3.14 × 10 × 14 </span>
<span>3.14 × 10 = 31.4 </span>
<span>31.4 × 14 = 31.4 × 10 + 31.4 × 4 </span>
<span>= 314 + 120 + 4 + 1.6 </span>
<span>= 434 + 5.6 </span>
<span>= 439.6</span>
Answer:
Acceleration = 3m/s²
Step-by-step explanation:
Here ,
Initial velocity = 30km/h
Final velocity = 0km/h
Time = 10s
Acceleration = ?
We know ,
A = v-u/t
or , A = 0-30/10
or, A = 30/10
A = 3m/s²
Therefore the acceleration is 3m/s²
Answer:
3 22/45
Step-by-step explanation:
I assume that the numbers are: 4,4,6,1,5,2,6
If so, then the MAD is 1.43
To find the MAD, you first find the mean of the list. It is 4.
Then find the absolute difference of each number from the mean.
Those values are: 0,0,2,3,1,2,2
Now find the mean of those numbers and you have about: 1.43
<span>let n+2=u
so, the equation became= [2/u]-[3/u]=5
=> [(2+3)/u]=5
=> 5/u=5
=> u=5/5=1
thus, u=1
we know u=n+2
so, n+2=1
=> n=1-2=-1
so, n=-1</span>
