The correct anser is D.

Circumference = 24πm, Width of track= 2 m

As we know that circumference = 2πr
Therefore, 2πr = 24π

r = 12m

Now, Radius of outer circle = Radius of inner circle + Width of the track = 12 m + 2 m = 14 m
Again, Circumference of outer circle = 2πR = 2 X 3.14 X 14 = 88 m

Hence, the quantity of wire required to surround the path completely is 88 m.

Perimeter of each square = 32 cm
⇒ 4 × side of square = 32 cm
⇒ Side of square = (32 ÷ 4) cm = 8 cm
∴ Perimeter of the figure = 10 × 8 = 80 cm

Quantity of flour Beena had =4 kg = 4000 g. Quantity of flour used to bake cake = 3 kg 60 g = 3060 gQuantity of flour left with Beena = 4000 -3060 = 940 gHence the correct answer is Option B

Class : Class 1

Quantity of flour Beena had = 4 kg = 4000 g
Quantity of flour used to bake cake = 3 kg 60 g = 3060 g
Quantity of flour left with Beena = 4000 – 3060 = 940 g
Hence, the right answer is Option B.

Option a. A is cooler than B because if you draw a number line,-4 is less than -1. When we go to the left it is decreasing and when it goes to right, it is ascending. Regards, class 6 boy Can't tell my name.

since, (-4) lies left to (-1) on a number line.so, -4< -1.: A is cooler than B
