The circumference of a circle is 15 meters. Find the area. Use 3.14 for π.
1 answer:
a = 17.9 meters^2
Given that:
• circumference of circle = 15 meters
T= 3.14
As we know that:
• circumference of circle = 2 nr
By putting values:
•15 = 2 (3.14) r
By simplifying:
• 15=6.28r
Dividing both sides by 6.28 we get:
• r= 2.39 meters
Now for finding area:
• Area = 1 r2
Putting values:
• Area = (3.14) (2.39)*2
By simplifying we get:
• Area = 17 .935 meters’2
So by rounding off radius to nearest tenth:
• radius =r=2.4 meters
Rounding off area to nearest tenth:
• area =a = 17.9 meters’2

Answer:
2923.34 in^3
Step-by-step explanation:
Volume = Pi x (r) ^2 x height
PI =3.14,
, R = 7inch (d =radius /2 >> 14/2)
H =19 inch
Volume = 3.14 x 49in^2 x 19 inch
= 2923.34 in^3
