The area of the circle is 6,358.5cm²

<h3>Area of the circle</h3>

The formula for calculating the area of a circle is expressed as;

  • A = πr²

r is the radius = x + y

r = 25 + 20 = 45cm

Substitute the given parameters into the formula to have:

A = 3.14(45)²

A = 6,358.5cm²

Hence the area of the circle is 6,358.5cm²

If DE = 8, PS = 4, and PQ = 3, then what is the scale factor of DEFG to PQRS?
posledela

The scale factor of DEFG to PQRS is: 3/8.

<h3>What is a Scale Factor?</h3>
  • A scale factor of a dilation is the number by which the size of an original figure is changed to a new figure.
  • Scale factor is ratio of corresponding side of new figure to original figure.

Thus:

DE corresponds to PQ.

PQRS is the new figure.

DE = 8; PQ = 3

  • Therefore:

Scale factor of DEFG to PQRS = PQ/DE

Scale factor = 3/8.

Thus, the scale factor of DEFG to PQRS is: 3/8.

-4(4y-10)+3(2y+8) simplify the expression
vagabundo [1.1K]

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

2.1     Pull out like factors :

  2y + 8  =   2 • (y + 4)  

Equation at the end of step  2  :

 (0 -  (4 • (4y - 10))) +  6 • (y + 4)

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  4y - 10  =   2 • (2y - 5)  

Equation at the end of step  4  :

 (0 -  8 • (2y - 5)) +  6 • (y + 4)

Step  5  :

Step  6  :

Pulling out like terms :

6.1     Pull out like factors :

  64 - 10y  =   -2 • (5y - 32)  

Final result :

 -2 • (5y - 32)
