Answer: 113.1

Step-by-step explanation:

Diameter = 12

We must find the radius. To do so, we divide the diameter by 2.

Radius = 6

Formula for finding the area of a circle: πr²

π = 3.14159265359

3.14159265359 × 6²

6 × 6 = 36

3.14159265359 × 36 = 113.097335529

Rounded to the nearest tenth = 113.1

The perimeter of the triangle at right is 52 units. Write and solve an equation based on the information in the diagram. Use you
marysya [2.9K]

Answer:

  • equation: (7x-4) +19 +(10x+3) = 52
  • x = 2
  • red: 10
  • blue: 19
  • yellow: 23

Step-by-step explanation:

The equation is based on the relation that the perimeter is equal to the sum of the side lengths.

  P = red + blue + yellow

  52 = (7x -4) +(19) +(10x +3)

  52 = 17x +18 . . . . . . . . . . . . . . simplify

  34 = 17x . . . . . . . . . . . . . subtract 18

  2 = x . . . . . . . . . . . . divide by 17

__

  red = 7(2) -4 = 10

  blue = 19

  yellow = 10(2) +3 = 23

Determine the currents in the picture
Evgesh-ka [11]

Answer:

The value of currents are I_1=0A, I_2=1A and I_3=1A.

Step-by-step explanation:

The Ohm's law states that

V=IR

It is given that the V₁=3V and V₂=4V.

In a parallel circuit:

→    Voltage is same in each component

→    Sum of the currents equals to the total current that flows.

I_2=I_1+I_3                   .... (1)

Equation for first loop is,

V_1=4I_1+3I_2

3=4I_1+3I_2              ..... (2)

Equation for second loop is,

V_2=1I_3+3I_2

4=1I_3+3I_2             ..... (3)

On solving (1), (2) and (3) we get

I_1=0

I_2=1

I_3=1

Therefore the value of currents are I_1=0A, I_2=1A and I_3=1A.
