Answer:
6.25 pi cm^2
Step-by-step explanation:
The formula for circumference is
C = 2*pi*r
We know the circumference is 5 pi
5 pi = 2 * pi *r
Divide each side by pi
5 pi/pi = 2 * pi *r/pi
5 = 2r
Divide by 2
5/2 = 2r/2
2.5 = r
We need to find the area of the circle
The area is given by
A = pi * r^2
= pi * (2/5)^2
= pi *6.25
= 6.25 pi cm^2
The 2 equations have no solution. If both are true, then
-3x + 3y = 4
-x + y = 4/3
Thus, 3 = 4/3, which is obviously wrong. Pls mark me as brainliest!
Answer:
The product of 1/2 and the sum of x and y. Or 1/2 times the quantity of x+y
Step-by-step explanation:
A sum is the answer to an addition problem and the product is the answer to a multiplication problem, sorry I don't really know how to explain it
