Answer:
26.4m is ur answwr pls mark branliest
Step-by-step explanation:
We know,
Circumference of circle = 2πr
Where,
r is radius of circle.
π is 22/7 or 3.14.
a. A circle with radius 63 cm.
r = 63 cm
Put r in circumference formula
\longrightarrow⟶ 2 × 22/7 × 63
\longrightarrow⟶ 44/7 × 63
\longrightarrow⟶ 2772/7
\longrightarrow⟶ 396
Therefore,
Circumference of circle is 396 cm.
b. A circle with diameter 8.4 m.
r = Diameter/2
= 8.4/2
= 4.2
Radius (or r) of circle is 4.2 m
Now, Put r in circumference formula :
\longrightarrow⟶ 2 × 22/7 × 4.2
\longrightarrow⟶ 44/7 × 4.2
\longrightarrow⟶ 184.8/7
\longrightarrow⟶ 26.4
Therefore,
Circumference of circle is 26.4 m.
Step-by-step explanation:
Now, we can easily write two rational numbers between 2 and 3. Hence, 73,83 are two rational numbers between 2 and 3.
