Answer: πr^2
Step-by-step explanation:
π is pie which is about 3.14
but you need to find the radius and square it is multiply it by itself (Example radius = 2 so 2x2=4)
then multiply the radius squared by π(pie) which is 3.14 or use a calculator.
Answer:
Step-by-step explanation:
4x+2y = -24 -------------(i)
<u> -4x+y = 12 -</u>------------(ii)
add (i) &(ii) 3y = -12
y = -12/3
y = -4
Put y = (-4) in (i)
4x + 2*(-4) = -24
4x - 8 = -24
4x = -24 + 8
4x = -16
x = -16/4
x = -4
