Answer:
A = 27π cm²
Step-by-step explanation:
Area of the shaded region = area of full circle of O - Area of the unshaded sector
= (πr²) - (θ/360*πr²)
Where,
r = 6 cm
θ = 360
Area of shaded region = (π*6²) - (90/360*π*6²)
= (36π) - (¼*π*36)
= 36π - 9π
Area of shaded region = 27π cm²

Answer:
$2561.50
Step-by-step explanation:
If the account earns simple interest, then the balance at the end of 6 months will be ...
... A = P + Prt . . . . . for principal amount P, interest rate r, time period t
... A = $2350 +2350·0.18·6/12 = $2350 + 211.50
... A = $2561.50
Answer: 120 percent increase
Step-by-step explanation:
72/60 = 1.2
1.2 times is also 120 percent
-- Subtract K from each side of the equation.
8/5 = 0
-- There is no value for K that can make this a true statement. So the original equation has no solution.
