Answer:

d = 2r or d = C/π

Diameter is equal to two times the radius or Circumference/π

C = 2πr

Circumference is equal to two times π multiplied the radius

A = π * r²

The area of the circle equals to π multiplied by the radius squared

Step-by-step explanation:

Let's find the formulas for d, C and A

d = diameter

C = Circumference

A = Area

r = radius

π ≅ 3.1416

d = 2r or d = C/π

Diameter is equal to two times the radius or Circumference/π

C = 2πr

Circumference is equal to two times π multiplied the radius

A = π * r²

The area of the circle equals to π multiplied by the radius squared

For each expression below, select the letter that corresponds to the equivalent expression given above.

11111nata11111 [884]

Part 1)
(x²+15x+65)+(2x-5)*(3x+8)
(x²+15x+65)+(6x²+16x-15x-40)
(7x²+16x+25)

the answer Part 1) is the letter B
(7x²+16x+25)

Part 2)
(4x+1)*(3x-4)-(5x²-10x-12)
(4x+1)*(3x-4)-(5x²-10x-12)
(12x²-16x+3x-4)-(5x²-10x-12)
(7x²-3x+8)

the answer Part 2) is the letter D
(7x²-3x+8)

Part 3)
(8x²+19x+4)+(3x+2)*(x-5)
(8x²+19x+4)+(3x²-15x+2x-10)
(11x²+6x-6)

the answer part 3) is the letter A
(11x²+6x-6)

Part 4)
(6x+1)*(3x-7)-(7x²-34x-20)
(18x²-42x+3x-7)-(7x²-34x-20)
(11x²-5x+13)

the answer Part 4) is the letter C
(11x²-5x+13)

Rewrite V=lwh to isolate the variable w then the literal equation becomes w=v/lh true or false

Oduvanchick [21]

Answer:

True

Step-by-step explanation:

$V=lwh\\\\lwh=V\\\\\frac{lwh}{lh}=\frac{V}{lh}\\\\ \boxed{w=\frac{V}{lh}}; l\neq 0$
