Please help immediately four equal circles are made with four corners of a square of side 7cm as their centers. The radius of each circle is 3.5cm
Calculate the area of the circular portions outside the square.

147π/4

Step-by-step explanation:

Area of one circle = π*r^2

r = 3.5 cm =7/2 cm

area = π*7/2*7/2 = 49π/4

therefore area of 4 circles =49π

As 1/4th circle is removed from each circle the shaded area = 3/4 area of the area of the circle.

therefore, the are of the shaded portion = 49π*3/4 = 147π/4

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
