Question

Find the radius of a sphere with a surface area of 804 cm

Answer 1

Multiple Chose:
9 cm
8 cm
64 cm
204 cm

Answer 2

surface area of the sphere = \[4 \pi r^2\]
\[804 = 4 \pi r^2 \rightarrow 804 = 4 \times \frac{22}{7} \times r^2\]

\[r^2 = \frac{ 804 \times 7}{4 \times 22}=\frac{ 5628}{88}=63.95 \approx 64 cm\]
\[r^2= 64 cm \rightarrow r= 8 cm\] is the radius o the sphere.
