Answer:
Step-by-step explanation:
Diameter = 6 units
Radius = Diameter/2 = 6/2 = 3 units
Taking π=3.14
Circumference = 2(π)(r) = 2(3.14)(3) = 6(3.14) = 18.84 = c
c = 18.84
Area = π(r)^2 = π(3)^2 = 9π =9(3.14) = 28.26 = b
b = 28.26
So,
b + c = 28.26 + 18.84 = 47.1
Answer:
b=6π the unit(cm)
c=18.84 the unit(cm)
b+c=
9+18.84=27.84
Step-by-step explanation:
circumference=c
diameter=d
radius=r
area=b
d=2r
6=2r
<u>6</u>=r
2
r=3
b=πr^2
b=3×3π
=9π
c=2πr
=2(3.14)3
= 3.14×6
=18.84

Answer:
Step-by-step explanation:
The bear can walk at a rate of 2 mph, which means after 4 hours it could have traveled 8 miles. That is our radius. To calculate the area of a circle, remember the formula
A =
r^2
3.14 * 8^2 = A
3.14 * 64 = A
200.96 = A
An area of
200.96 square miles must be searched.
