Answer:
2.768 is the answer
Step-by-step explanation:
As we knw that the dr/dt = 2
And The area of the circular slick is given by formul
A = (pi)r^2.
Now lets take derivative:
<span>dA/dt=2πrdr/dt
As we knw that radius is 25
so</span><span>dA/dt=2π(25)(2)=100π
which is equal to
=314.16 per minute this is how area is increasing
now for part b
</span><span> t = 4, the radius will have increased to 8 m.
now we will put the values in formula dr/dt
</span>so it will be.dA/dt=2π(8)(2)
=32π
=100.53 is the answer
hope it helps
Step-by-step explanation:
5) angle 5 = 69°
than, angle 10 = 69° ( alternate interior angle )
6) angle 6 = 115° ( alternate interior angle )
7) angle 7 = 118° ( alternate interior angle )
8) angle 11 = angle 4 - 180
→ 72 - 180 = 108°
therefore, angle 11 = 108°
9) angle 14 = 114° - 180
→ angle 14 = 66°
10) angle 12 = 86° ( alternate interior angle)
hope this answer helps you dear...take care!
Answer:
96 feet
Step-by-step explanation:
Given : A square garden has a diagonal of 34 ft. Colton wants to put a fence around the entire garden.
To Find: How much fencing will he need? Round to the nearest foot.
Solution:
Formula of diagonal of square = 
Where a is the side of the square.
Since we are given the diagonal length of square garden = 34 ft.
So, 


Thus the side of the square garden is 24.04 ft.
Now we are supposed to find how much fencing is required
So, we are supposed to find the perimeter of square.
Perimeter of square = 
= 
= 
Thus he need 96.16 ≈ 96 feet fencing .
