Given:
4. Diameter of the circle, d = 58 yd.
6. Diameter of the circle, d = 10.2 m
Required:
We need to find the circumference of a circle.
Explanation:
4.
Consider the formula to find the radius.
[tex]Radius\text{ =}\frac{diameter}{2}[/tex]Substitute diameter = 58 in thr formula.
[tex]Radius\text{ =}\frac{58}{2}=29yd[/tex]Consider the formula to find the circumference of a circle.
[tex]C=2\pi r[/tex]Substitute r =29 in the formula.
[tex]C=2\times3.14\times29[/tex][tex]C=182.12\text{ yd }^2[/tex]Answer:
The circumference of a circle is 182.12 square yards.
6)
Consider the formula to find the radius.
[tex]Radius\text{ =}\frac{diameter}{2}[/tex]Substitute diameter = 10.2 in thr formula.
[tex]Radius\text{ =}\frac{10.2}{2}=5.1m[/tex]Consider the formula to find the circumference of a circle.
[tex]C=2\pi r[/tex]Substitute r =5.1m in the formula.
[tex]C=2\times3.14\times5.1[/tex][tex]C=32.028\text{ m}^2[/tex][tex]C=32.03\text{ m}^2[/tex]
Answer:
The circumference of a circle is 32.03 square meters.
