Circle A has a radius of 21 meters . Circle B has a radius of 28 meters. Find the circumference if each circle in terms of pi

qwelly [4]

Answer:

Circle A= $42\pi$

Circle B = $56\pi$

Step-by-step explanation:

Circumference of a circle = $2\pi r$

Since you are given the radius, you put it in place of r

Circle A = $2 *\pi *28\\21*2 = 42\\\\42\pi$

Circle B= $\\2*\pi *28\\28*2 =56\\56\pi\\\\\\$

Which equation could be used to find the height of the flagpole?

Andrew [12]

Given a fragpole which makes a right angle with the point of observation with the angle of elevation as 50°.

Let x be the height of the flagpole, then

$\sin50^o= \frac{x}{5}$

Therefore, the equation that could be used to find the height of the flagpole is
x/5 = sin 50

Answer:

a=$10

c=$3

Step-by-step explanation:

Step one:

given data

let adults tickets be a

and child tickets be c

Roy's purchase

6a+2c=66------1

Elisa's purchase

5a+4c=62-------2

Hence, the system of equations

6a+2c=66------1

5a+4c=62-------2

solving simultaneously

6a+2c=66------1 x2

5a+4c=62-------2 x1

12a+4c=132

-5a+4c=62

7a=70

divide both sides by 7

a=$10

put a=70 in 1

6(10)+2c=66------1

60+2c=66

2c=66-60

2c=6

c=$3

4. Given the perimeter find the missing side.

kakasveta [241]

Answer:

x^2 + 3x + 5

Step-by-step explanation:

sum of the two given side = 2x^3 + 3x^2 + 3x -2

missing side = 2x^3 + 4x^2 + 6x + 3 - 2x^3 - 3x^2 - 3x + 2 = x^2 + 3x + 5
