Example 1: If the radius of a circle is 30 cm, find its circumference. Solution: r = 30 cm Use the formula to find the circumference of a circle: C = 2\(\pi r\) [Write the formula] = 2 x 3.14 x 30 [Substitute the value of r and \(\pi\)] = 6.28 x 30 = 188.4 Therefor...
Example 2. Find the perimeter of the semicircular region. Solution: As per the given question, divide the circumference by 2. \( \frac{C}{2}=\frac{\pi d}{2} \) \( =\frac{3.14\times 2}{2} \) (Substitute 3.14 for \( \pi \) and 2 for “d”) \( =\frac{6.28}{2} \)...
How to find the circumference of a circle with the area of 169πm2 (in the terms of π)? Circles- Area and Circumference: On the planner space, a circle is a closed geometry with such that this closed geometry has a constants distance from a fixed point known ...
Step 2: To find the circumference of the circle when the radius is given plug in the value of radius found in step 1 in the formula $$C = 2\pi{r} $$ To find the circumference of the circle when the diameter is given plug in the value of diameter found in step 1 in the ...
The circumference a circle can also be represented in terms of the radius of the circle.We can define the radius of a circle in terms of the diameter through the relationship: d=2∗r Substituting this into the previous equation to find circumference of the circle, we get: ...
Circumference or perimeter of the pool Surface area of the water Water volume contained by the pool. The specific formulas used to derive these measurements will vary, depending on the shape of the pool, and calculations can be easy or difficult, depending on that shape. A rectangular pool tha...
You can find the circumference of a circle by using the measurement of its diameter, radius or area. The circumference of a circle is the distance around the circle's edge from one point, meeting back at that point. Knowing how to calculate a circle's ci
The sector of a circle is a partition of that circle. A sector extends from the center, or origin, of the circle to its circumference and encompasses the area of any given angle that also originates from the center of the circle. A sector is best thought of as a piece of pie, and ...
