The surface area of a sphere is found using the formula sa=4πr^2 where r is the radius. if the surface area of a sphere is 144π square feet, what is the radius, in feet

144= 4. 3.14.r²
r² = 144/12.56
r=√11.46
r= 3.38

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.

The answer is d 18ft
