Step-by-step explanation:
Answer: 4π cm or 12.56 cm
Step-by-step explanation: To find the circumference of this circle, start with the formula for the circumference of a circle which is C = 2πr.
Since the radius is 2 centimeters, we can
plug in 2 centimeters for <em>r</em> in the formula.
So we have (2)(π)(2 cm) which is equal to 4π cm.
So the circumference of this circle is 4π cm.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (4)(3.14) which is equal to 12.56.
So the circumference of the circle is
approximately equal to 12.56 cm.
It’s B thank you can I plz have brainlist plz
Answer:
h = f/7g
Step-by-step explanation:
You have to rearrange the equation so that h is alone on one side.
f = 7gh
f/7g = (7gh)/(7g)
f/7g = h
h = f/7g
ANSWER:84.823 sq.cm (approx.)
Area of shaded region,
=Area of whole circle-Area of the quadrant AOB which is cut out.
=π*6*6-(π*6*6)/4 sq.cm
=36π-9π sq.cm
=27π sq.cm
=84.823 sq cm(approx.)
