Answer:

1.If r = 6 cm, the the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm. Suppose you only know the diameter

2.r = 11 d = 22 C = 69.1A = πr2 = π(d2)2 A = C24π π = 3.1415 A = area C = circumference or perimeter r = radius, d = diameter

3.Given, diameter of the circle = 10 cm,

∴Radius=2D=210=5cm

Answer:

GIVEN:

RADIUS=6cm

FORMULA:

A=πr²

SOLUTION:

[tex]a = \pi \: r {}^{2} \\ a = 3.14(6) \\ = 113.09734 \: or \: 113.1cm {}^{2} [/tex]

GIVEN:

RADIUS=11cm

FORMULA:

A=πr²

SOLUTION:

[tex]a = \pi \: r {}^{2} \\ = 3.14(11) \\ = 380.13cm {}^{2} [/tex]

GIVEN:

DIAMETER=10cm

RADIUS= ½ of diameter

= 5

FORMULA:

A=πr²

SOLUTION:

[tex]a = \pi \: r {}^{2} \\ = 3.14(5) \\ = 78.54m {}^{2} [/tex]

Have a good day!
