Answer:
<em>8 units</em>
Step-by-step explanation:
Given the relationship between the radius, r, of a sphere and its surface area, A expressed as;
r = 1/2( A /4 π )
We are to find the radius r when Area A is 64π
Substitute A = 64π into the expression and get r as shown;
Recall that: r = 1/2( A /4 π )
r = 1/2( 64 π/4 π )
r = 1/2(16)
r = 16/2
r = 8units
<em>Hence the radius of the sphere will be 8 units</em>
