Angle a=35° (Vertically Opposite Angles)

Angle b= 180°-90°-35° =55° (Sum of angles in a triangle)

Angle c=180°-70°=110° (Angles on a straight line)

Find the surface area of a cylinder with a base diameter of 8ft and a height of 6ft. Write your answer in terms of pi, and be su

Ksju [112]

Given that diameter of the base of the cylinder = 8 ft

Given that height of the cylinder = 6 ft

We have to find the surface area of the cylinder in terms of pi.

So we need to use formula of surface area of the cylinder which is

$Area= 2\pi r(r+h)$

where h= height = 6

r= radius = diameter/2 = 8/2 = 4

Now plug these values into above formula

$Area= 2\pi *4(4+3)$

$Area= 2\pi *4(7)$

$Area= 2\pi *28$

$Area= 56\pi$

Hence final answer is

$Area= 56\pi$ square ft

Answer:

2. quadrant 4

3. quadrant 2

4. quadrant 3

Step-by-step explanation:

You can refer to the picture.

2. Since $tan\theta$ less than 0 which means $tan\theta$ is negative, $sin\theta$ less than 0 which means $sin\theta$ is negative.

So, the angle lies in quadrant 4 (Cos quadrant)

3. Since $tan\theta$ less than 0 which means $tan\theta$ is negative, $cos\theta$ less than 0 which means $cos\theta$ is negative.

So, the angle lies in quadrant 2 (Sin quadrant)

4. Since $tan\theta$ more than 0 which means $tan\theta$ is positive, $sin\theta$ less than 0 which means $sin\theta$ is negative.

So, the angle lies in quadrant 3 (tan quadrant)

5. A family spends T 600.00 a day for food which is 40% of the

BabaBlast [244]

Answer:

Step-by-step explanation:

<h3>First , We will solve their daily Income </h3>

• Income = spends / rate

• Income = 600 / 40%

• Income = 600 / 0 .40%

• Income = 1500

Thus , Their daily Income is 1500 . Now ,We will solve for the rate of the Allowance .

• Rate = spent / Income

• Rate = 225 / 1500

• Rate = 0.15

• Rate = 15%

Therefore, the percent of the family's daily Income of the Allowance of their children's is 15%
