D=6.3 mm caculate the area of the circle.

Hello!

The area of a circle is given using the formula: A = πr².

Given that the diameter is 6.3 millimeters, we need to find the radius. Remember, the radius of a circle is half the diameter.

R = 6.3 / 2 = 3.15 millimeters

With the radius, we can substitute the values into the formula and solve.

A = π(3.15)²

A = 9.9225π

A = 9.92π (not multiplying by π), 31.17 (multiplied by π), 31.16 (multiplied by 3.14)

Therefore, the area of the circle is about 31.17 millimeters squared.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
