Answer: 1324.12 sq. cm.

Step-by-step explanation:

A=2πrh+2πr2

A = 2π x 8.2 x 17.5 + 2π x 8.2^2

A = 2π x 143.50 + 2π x 67.24

A= 1324.12

Answer:

SA = 1324.1 cm²

Step-by-step explanation:

Surface Area of Cylinder = 2\pi rh+2\pi r^2

<u><em>Where r = 8.2 cm, h = 17.5 cm</em></u>

=> SA = 2(3.14)(8.2)(17.5)+2(3.14)(8.2)^2

=> SA = 901.6+2(3.14)(67.24)

=> SA = 901.6 + 422.5

=> SA = 1324.1 cm²

Escribe el nombre de algún tipo de ángulo que se forma "Entre Dos rectas Paralelas y una Secante"
blsea [12.9K]

Answer:

We see that opposite angles are two angles between two secant lines (“secant lines” simply means two lines that cross each other) that share a vertex (that is why they are called “vertical” angles). We see also that they are not adjacent (which means next to each other) but opposite each other.

Step-by-step explanation:

Vemos que los ángulos opuestos son dos ángulos entre dos líneas secantes (“líneas secantes” simplemente significa dos líneas que se cruzan) que comparten un vértice (por eso se llaman ángulos “verticales”). También vemos que no son adyacentes (lo que significa uno al lado del otro) sino uno frente al otro.

SOMEONE PLS HELP I WANT TO GO TO BED AND EXPLAIN HOW TO PLS
vlabodo [156]

Answer:

40 degrees

Step-by-step explanation:

2x-30+x=90

Then you add x to 2x which will be 3x so now its

3x-30=90

add 30 to both sides

3x=120

divide 3 from both sides

x=40

Since Angle QPR is virticle to 2x-30+x=90

Angle QPR is 40 degrees

B(n)=-4-2(n-1) <br> find the12th term in the sequence
bixtya [17]

Answer:

The 12th term in the sequence is b(12)= -26

Step-by-step explanation:

For the 12th term, that means we need to find what the value of b is when n=12

To find b:

  • Substitute all 'n' with 12 (since its the 12th term)

                    b(n)= -4-2(n-1)

                    b(12)= -4-2(12-1)

  • Solve the equation in order of BEDMAS (aka PEDMAS)

                    b(12)= -4-2(11)

                            = -4- (2*11)

                            = -4-(22)

                            = -26

The  12th term in the sequence is b(12)= -26
