Answer:

Step-by-step explanation:

1) we have to find the area of the cut out portion

Since both circles in one side makes up the side 28cm

The diameter of each circle is 14cm

radius = diameter / 2

r = 7cm

Area of a circle = πr²

A = 22/7 × 7²

= 22/7 × 7 × 7

= 22 × 7 = 154cm²

So the four circles will make

= 154 + 154 + 154 + 154

= 616 cm²

The Area of the square will be

= L × L

= 28 × 28

= 784 cm²

Therefore the area of the remaining portion will be

Area of the square - total area of the circles

= 784 cm² - 616 cm²

= 168 cm²

The area of the remaining part is 168 cm²

Answer:

168 cm²

Step-by-step explanation:

square- 4circles

Area of square = 28² = 784

Radius of circle = 28/4 = 7

Area of 4 circles = 4[(22/7)×7²)] = 616

Shaded area = 784-616 = 168 cm²

dedylja [7]

Answer: C. $\dfrac{1}{3}$

Step-by-step explanation:

Given: Box contains 8 green balls and 4 purple balls.

Total balls = 8+4 = 12

event 1 = first picking green ball

event 2 = second picking purple balls.

As first ball was replaced, that means both events are independent.

Probability that you have selected a green ball and then a purple ball = P(purple ball )

Formula for probability = $\dfrac{\text{favorable outcomes}}{\text{total outcomes}}$

Probability of selecting a purple ball (second pick)= $\dfrac{4}{12}$

$=\dfrac{1}{3}$

The required probability $=\dfrac{1}{3}$ , so C is correct option.
