Answer:
r = 5 m
Circumference = 31 m
Area = 79 m²
Step-by-step explanation:
Finding area of circle and circumference of circle:
25) Radius is the distance between the center of the circle and the point on the circle. Radius is half of diameter.
Diameter = 10 m
[tex]\sf radius = \dfrac{diameter}{2} \\\\\\~~~~~~~~ =\dfrac{10}{2}[/tex]
[tex]\boxed{\bf r = 5 \ m}[/tex]
26) Circumference of circle:
[tex]\boxed{\bf circumference \ of \ the \ circle = 2\pi r}[/tex]
= 2 * 3.14 * 5
= 31.4
= 31 m
27) Area of circle:
[tex]\boxed{\bf Area \ of \ circle = \pi r^2}[/tex]
= 3.14 * 5 * 5
= 78.5
= 79 m²
