Well first, we must remember the formula for the area of a circle.
The formula for the area of a circle is:
PiR^2, or Pi • R^2.
Basically this means 3.14 (Pi) • R • R (Radius).
We have our radius, 4, so we can plug in our numbers to solve.
3.14 • 4 • 4 is our formula, so let's solve.
4 • 4 = 16.
16 • 3.14 = 50.24.
Remember when we solve for the area, we use units squared (units^2).
Your answer is 50.24 cm^2.
I hope this helps!
It would be (b) 3/5 because
Terminating decimal is a decimal with a definite amount of digits, meaning that it stops after a certain digit.
The other answers:
(A) 3/7 = 0.42857143.....
(C) 1/3 = 0.333333333333.....
And (D) = 0.27272727272.....
And only 3/5 (B) stops after a certain digit because it's decimal value is 0.6.
Hope this helps!
1212 km in 3 min
3min • 20= 60 min = 1 hour
1212km • 20 = 24, 240km
Theres a website called spades (or something like that) if you go on it look for your math text book and it will have the answers for you
