900,000+80,000+500+7 is 980,507
Answer:
17
Step-by-step explanation:
all 4 numbers added up, 68, divide by the amount of numbers, which is 4, and you get the answer
c = circumference
pi = 3.14
r = radius = 9 inches
d = diameter
c=pi*d
The radius is half of the diameter, d = 2r. Then d = 2*9=18.
plug into equation. c= pi*d = 3.14*18
round accordingly and you may want to include that the measurement you end up with is in inches.
Step-by-step explanation:
Hey there!
Given;
Radius of a circle (r) = 7cm
Now;
We know that;
Area of circle (a) = π*(r^2)
= 3.14*(7^2)
= 3.14*49
= 153.86 cm^2
Therefore, the area of a circle is 153.86 cm^2.
