Answer:

circumference: 62.8 ft
area: 314 ft²

Step-by-step explanation:

The circumference is given by the formula ...

C = πd

Using the given numbers, the circumference is ...

C = (3.14)(20 ft) = 62.8 ft

The area is given by the formula ...

A = πr² . . . . . where radius r is half the diameter

Using the given numbers, the area is ...

A = 3.14(10 ft)² = 314 ft²

The area of rectangle with length l and width w is

$A=l\cdot w.$

If the length of rectangle is expressed as $l=3x^2 + 5x + 10$ and the width of rectangle is expressed as $w=x^2-3x-1$ , then the area of rectangle is

$A=(3x^2 + 5x + 10)(x^2-3x-1)=3x^4-4x^3-8x^2-35x-10.$

Answer:

Step-by-step explanation:

(c − b)^2 + a^2

Let a = –5, b = –2, and c = –4.

(-4--2)^2 + (-5)^2

(-4+2)^2 + (-5)^2

(-2)^2+ (-5)^2
