It is 48 cm
Circle, followed by square. circumference = 2 pi r so pi r = 50 so r = 50/pi; Area of circle = pi r2, = 2500/pi = 795.5 sqcm Square = 25 x 25 = 625 sqcm.
Shirley...! 3 x 3 = 9 sqcm

Given this area, the sides measure 52.92734 cm
There are 2.54cm per inch. So this being a square function multiple 2.54x2.54=6.4516 take total sqcm and divide by 6.4516. Example 4"x4"=16"sq (4x2.54=10.16) x (4x2.54=10.16) 10.16x10.16=103.2256 sqcm 103.2256sqcm/6.4516=16"sq
10.5 x 10.5 x pi = 346.5 sqcm
Surface area of a sphere = 4*p*radius2 4*pi*radius2 = 2916 Divide both sides by 4*pi: radius2 = 232.047907 Square root both sides: radius = 15.23311875 cm
silicon solar cells of 2 sqcm produces 0.5V and power of 0.7W. So to get 20Volts 40 solar cells are to be connected in sieries.
The half page of the magazine is 15cm x 12cm (half of 24cm). So, the area of the half page advertisement is 180 sqcm. At Rs 300 per 10 sqcm, the total cost for the half page advertisement would be Rs 5400 (180 sqcm * Rs 300).
