Option (d) is correct, Radius of another circle is 32 cm.
Math
5 points
Step-by-step explanation:
Given that,
Radius of first circle is 8 cm.
We know,
Area of circle = πr²
\longrightarrow
\longrightarrow
Area = 22/7 × (8)²
\longrightarrow
\longrightarrow
Area = 22/7 × 64
\longrightarrow
\longrightarrow
Area = 1408/7
Thus,
Area of first circle is 1408/7 cm².
Now,
It is also given that Area of another circle is 16 times of first circle
\longrightarrow
\longrightarrow
1408/7 × 16
\longrightarrow
\longrightarrow
22528/7
Area of another circle is 22528/7 cm².
Now,
\longrightarrow \sf \pi r^{2} = \dfrac{22528}{7}
\longrightarrow \sf \pi r^{2} = \dfrac{22528}{7}
