From a circular sheet of radius 18cm , two circles of radii 4.5cm and a rectangle of length 4cm and breadth 1cm are removed; fin
d the area of the remaining sheet.
1 answer:
Answer: 14 cm
Step-by-step explanation:
Answer:
R=14 cm
total area= πr²
=22/7*196=616 cm²
r2= 3.5 cm
area of the small circles= 2*πr²=2*12.25*22/7=77 cm²
length of rectangle=3
breadth=1
area =lb=3 cm²
area of the small circles+area of rectangle=77+3=80 cm²
remaining area=616-80=536 cm²

Answer:
No.
Step-by-step explanation:
2(5x-3) + 6x is equal to 16x-6:
Distribute:
=(2)(5x)+(2)(−3)+6x
=10x+−6+6x
Combine Like Terms:
=10x+−6+6x
=(10x+6x)+(−6)
=16x+−6,
Which is not equal to 16x-3
