Answer:
what is the radius of 7 meters??
Inputs: 7
Radius: 14
Diameter: 43.98
Circumference: Meter
The area of a circle with radius 7 is 153.9
Formula:
r = 7
d = 14
C = 44
A = πr2 = π(d
2
)2 A = C2
4π
π = 3.1415
A = area
C = circumference or perimeter
r = radius, d = diameter
Solution Steps:
Area of a circle in terms of radius:
Area = π·r2 = 3.14·72 = 153.9 square meters(*)
Area of a circle in terms of diameter:
Area = π·(d
2
)2 = 3.14·(14
2
)2 = 3.14·(7)2 = 153.9 square meters(*)
Area of a circle in terms of circumference:
Area = C2
4π
= 43.982
4π
= 1934.24
(4·3.14)
= 1934.243
12.56
= 153.9 square meters (*)
Hope it helps (^^)
