Hey!
Your answer is solved below/above idk wherever just see in the picture.
(2/7)^2 x (7/9)^2
((2^2)/(7^2)) x ((7^2)/(9^2))
(4/49) x (49/81)
*Cross multiply*
(4/81)
Answer:
<u>66.22 </u>times 10=662.2
<u>4.03 </u>times 100=403
<u>0.108 </u>times 1000=108
Step-by-step explanation:
662.2 ÷ 10
403 ÷ 100

Answer:
❥
Diameter of a circle is 8 cm. Then find out the area and perimeter of the circle.
❥
Area of circle is 50.29(≈)cm² and perimeter of circle is 25.14(≈)cm.
❥
•Given :-
Diameter of the circle = 8 cm.
•To find :-
Area and perimeter of the circle.
• Solution :-
Let the radius of the circle be r cm.
Diameter = 8 cm.
We know,
★
So, Radius (r) = 8/2= 4 cm.
We know,
★
Area of circle= πr²
→Area of circle=
→Area of circle=
→Area of circle= 50.29(≈)cm²

We know,
★
Perimeter of circle= 2πr
→ Perimeter of circle=
→Perimeter of circle=25.14(≈)cm
