Answer:

The correct answer is third option

 π(3)(5) + π3²

Step-by-step explanation:

<u>Points to remember</u>

Surface area of cone = πrl + πr²

Where r is the radius of the cone and l is the slant height of cone

<u>To find the correct answer</u>

Here r = 6/2 = 3 in

l = 5 in

Surface area =  πrl + πr²

 =  π(3)(5) + π3²

The correct answer is third option

 π(3)(5) + π3²

Answer:

Third option

Step-by-step explanation:

By observing the diagram we can see that the diameter of circular base is 6 inches. The diameter will be sued to find the radius.

r = 6/2 = 3 inches

We can also see from the diagram that lateral height denoted by l is 5 in.

We know that the formula for surface area of a cone is given by:

SA = \pi rl+\pi r^2\\Putting\ the\ values\ of\ r\ and \l\\SA = \pi (3)(5)+\pi (3)^2

Comparing it with the options we get that the third option is correct ..

Anarel [89]

Answer:

a) There is suggestive evidence the velvet leaf seed is successful at weed control.

b) Lower bound: 3.699 Upper bound: 6.629

c) Since the confidence interval contains the average percent of seeds to be infected by the beetle (5.164), so we fail to reject the null hypothesis at the specified level of significance.

Step-by-step explanation:

Solve the equation -2.6b + 4 = 0.9b - 17
Soloha48 [4]
If you are solving for b:
-2.6b+4=0.9b-17 <subtract 4 from both sides
-4 -4
-2.6b =0.9b-21 <subtract 0.9b from both sides
-0.9b -0.9b
-3.5b = -21 <divide by -3.5
--------- ------
-3.5 -3.5

b=6

WhaT is the sum of the first 6 terms of this geometric system<br> -5,10,-20,40,...
jeyben [28]
Each one is multiplied by -2...

PROOF
-5 * 10 = -20
-20 * -2 = 40
And so on.

So we need two more numbers so do 40 * -2...

40 * -2 = -80

And then...
-80 * -2 = 160

So the first 6 numbers are...
-5, 10, -20, 40, -80, 160.

We need to find the SUM, which is all the numbers added together.

-5 + 10 - 20 + 40 - 80 + 160 = 105

105 is your answer.

tensa zangetsu [6.8K]
So I’m thinking of this as two triangles. So I would do 16x8/2 which equals 64 and 10x6/2 which equals 30. So my guess is that the area is 94in^2. Hope this helps you out!
