3.

Perimeter of rectangle is 151m.if breadth is 32.find lenth

Answer»

Given

PERIMETER of Rectangle is 151m

Breadth of Rectangle is 32m

To Find

Length of Rectangle

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

Perimeter of Rectangle =2(length +breadth)

=>Perimeter of Rectangle =2(L +32)

=>151=2(l+32)

=>151/2=l+32

=>151/2-32=l

=>151-64/2=l

=>87/2=l

=>43.5=l

∴Length of Rectangle is 43.5m

Check

Perimeter of Rectangle=>2(43.5+32)

Given line PQ of length 4.2 cm, construct line AB such that the length of line AB is twice that of line PQ. Verify by measurement.

Answer»

Given : line PQ of length 4.2 cm,

To Find : CONSTRUCT line AB such that the length of line AB is twice that of line PQ.

Verify by measurement.

Solution:

Step1 : Draw a line segment PQ = 4.2 cm

Step 2 : Draw a ray AX

Step 3 : Using Compass width = PQ and taking A as CENTER cut ray AX at Y

Step 4 : Keeping Compass width same and taking Y as center cut ray AX further at B

AB = AX + XY

=> AB = PQ + PQ

=> AB = 2 PQ

=> AB = 2(4.1)

=> AB = 8.2 cm

Measure AB by scale/ruler

AB = 8.2 cm

Hence Verified

50.

Curved surface is 24200cm^2 radius is 35cm find the height

Answer»

Answer:

Hii friend,

Height of cylinder = 35 cm

CSA of cylinder = 2πrh

24200 = 2πrh

24200 = 2×22/7×r×35

r = 24200 ×7/44×35

r = 169400/1540

r = 110

Hence,

The RADIUS of cylinder = 110 cm.

HOPE IT WILL HELP YOU... :-)
