The area of this circle is 96π m². what is the area of a 30º sector of this circle?
dlinn [17]
Answer: 8π square meters

Explanation: 

First, we convert the angle of the sector to radians, which is 30 degrees. 

Note that 180 degrees is equal to π radians. Since 30 degrees is equal to 180 degrees divided by 6, 

30 degrees = π/6 radians

Thus, the angle of the sector in radians is π/6.

So, the area of the sector is given by 

(Area of sector) = (1/2)(radius)²(angle of the sector in radians)
                          = (1/2)(radius)²(π/6)
                          = (π/12)(radius)²
                          = (1/12)(π)(radius)²

Note that

(Area of the circle) =  (π)(radius)² = 96π

Therefore, the area of the 30-degree sector is given by 

(Area of the sector) = (1/12)(π)(radius)²
                                = (1/12)(Area of the circle)
                                = (1/12)(96π)
(Area of the sector) = 8π square meters

(7a-b+3)-(-2a-8b+8)
Apply plus/minus rule.
-(-a)= a and -(a)=-a
we get
(7a-b+3)-(-2a-8b+8)= 7a-b+3+2a+8b-8
Add like terms

Sharon is jumping from an 18-foot diving board with an initial upward velocity of 4 ft/sWhen Sharon jumps, Megan throws a beach
likoan [24]

Answer:

1.08 seconds

Step-by-step explanation:

given data

<u>first equation:</u>

According to the data, sharon position will be

h(t)= -16 t^{2} + 4t +18---->eq(1)  

<u>Second equation;</u>

When Sharon jumps, Megan throws a beach ball up to Sharon with an initial upward velocity of 16 ft/s from a height 5 feet off the ground to the nearest hundredth of a second

therefore, ball position would be

h(t)= -16t^{2} +16t +5 --->eq(2)

In order to find how long after she jumps does the ball reach Sharon i.e time, we will equate eq(1) and eq(2)

Therefore,

eq(1)= eq(2)

-16t^{2} +4t +18 = -16t^{2} + 16t +5  --->(further simplifying it)

-16t^{2} + 16t^{2} + 18 -5 = 16t - 4t

13 = 12t

t= 13/12

t= 1.08 s

Thus it took 1.08 seconds.
