Use 3.14 for pi and round to the nearest hndredth.
If r=7m, then d= ?, and c= ?
not enough info to find d and c
post the whole problem
d = 0.49 c = 7.0 a = 0.14

d = 0.49 c = 7.0
d=0.49 c= 7.0 a=0.14
R=7m d= C=
C=43.96
d=14m
To find the diameter (d) given the radius (r), you simply multiply the radius by 2. In this case, the radius (r) is 7m, so the diameter (d) would be 7m x 2 = 14m.
To find the circumference (c) of a circle, you can use the formula c = π * d, where π is the mathematical constant pi and d is the diameter. In this case, π is rounded to 3.14 and the diameter (d) is 14m. So, the circumference (c) would be 3.14 * 14m = 43.96m, rounded to the nearest hundredth.
Therefore, the diameter (d) would be 14m, and the circumference (c) would be 43.96m (rounded to the nearest hundredth).
