find the circumference and area of a circle if its diameter is 12 feet. round to the nearest tenth.
whats the answer??? 1/4?
wat the fudge
i asked for the answer
ugh! come on just this one plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
yall made me putted the wrong answers for allll the problems
To find the circumference and area of a circle, we can use the formulas:
Circumference = π * diameter
Area = π * (radius)²
First, let's find the circumference.
Given that the diameter is 12 feet, we can use the formula for the circumference of a circle, which is C = π * d.
Plugging in the value of the diameter (d=12) into the formula, we get:
Circumference = π * 12
Now, since we want to round our answer to the nearest tenth, we can use the approximate value of π as 3.14.
Calculating the circumference:
Circumference = 3.14 * 12 = 37.68
Rounded to the nearest tenth, the circumference is approximately 37.7 feet.
Next, let's find the area of the circle.
Given that the diameter is 12 feet, we can first calculate the radius by dividing the diameter by 2.
Radius = diameter / 2 = 12 / 2 = 6 feet
Plugging the value of the radius into the formula for the area of a circle, which is A = π * r^2, we get:
Area = π * 6^2
Calculating the area:
Area = 3.14 * 6^2 = 3.14 * 36 = 113.04
Rounded to the nearest tenth, the area is approximately 113.0 square feet.
Therefore, the circumference of the circle is approximately 37.7 feet and the area is approximately 113.0 square feet.
pi D = circumference
(1/4) pi d^2 = areea
No. The answer is not 1/4.
Please use the formulas that Damon posted.
