Answer:

Step-by-step explanation:

radius of the circle=12 cm / 2=6 cm

Area of the square=side²=(12 cm)²=144 cm²

Area of the circle=πr²=(3.142)(6 cm)²≈(3.142)*36 cm²≈113.112 cm²

Area of the four sides between the square and the circle=

=Area of the square - area of the circle=144 cm²-113.112 cm²=30.888 cm²

shaded area =30.888 cm²/4=7.722 cm²

Answer =7.722 cm²

Andre45 [30]

Answer:

6.1 seconds

Step-by-step explanation:

The correct question is

A helicopter flying at an altitude of 600 ft dropped a package to a lifeboat. Use the formula t= √h/4 to find how many seconds it takes for the package to reach the lifeboat. Round your answer to the nearest tenth of a second

we have

$t= \frac{\sqrt{h}}{4}$

substitute the value of h in the formula

$h=600\ ft$

$t= \frac{\sqrt{600}}{4}=6.1\ sec$
