Circumference
2*pi*r
2*(22/7)*(9/2)
2*(11/7)*9
198 / 7
28.28 cm
so 56.52 is not correct
Answer:
62.79%
Step-by-step explanation:
70-43 = 27
X/100 = 27/43
(27 * 100)/43
= 62.79%
Answer:
A = 50.26 sq meters
Step-by-step explanation:
we have to find the diameter first by using the circumference:
C = πd
25.12 = πd
25.12/π = d
8 = d
this means the radius is 4
A = πr²
A = π4² or 16π
A = 50.26 sq meters
3/4-3=43 Thsts the answer hopes it help
