Area of a circle is πr^2.
The radius of the smaller circle with diameter 10 cm is 5 cm.
The radius of the larger circle with diameter 20 cm.is 10 cm.
Area of larger circle : Area of smaller circle
Area of larger circle = 100π.
Area of smaller circle = 25π.
Ratio = 100π : 25π or 100π/25π.
Answer:1.5
Step-by-step explanation:
12.6j + 8 = 10.2j +4.4
2.4j=3.6
j=3.6/2.4= 1.5
Answer: 4y+4z
Step-by-step explanation:
Answer:
1/2 of 4/5 = 1/2 of four fifths = two fifths
Step-by-step explanation:
1/2 x 4/5 = 4/10
4/10 simplified is 2/5
4 divided by 2 = 2
---- ----
10 divided by 2= 5
