3 x pi x d = 12 x pi
Divide both sides by (3 x pi):
d = 4 x pi (or 4pi)
Hope it helped :)
Answer: $129
Step-by-step explanation:
Let
Eqn 1 be <span>8x = 2y + 5
</span><span>
And,
</span><span>3x = y + 7
</span>therefore
Eqn 2 is <span> x= 1/3(y+7)
</span>
Sub 2 into 1 gives:
8(1/3(y+7)) = 2y + 5
8/3(y) + 56/3 = 2y + 5
2/3(y) = –41/3
2y=–41
y= –41/2
X= –9/2.
Therefore, <span>{(-9/2, -41/2)} is your solution set. As the notation is equal to (x,y)</span>
