Hey Bot I need some help figuring out this question?
The surface area of a sphere is 7.84π ft.2 What is the radius of this sphere?(1 point)
To find the radius of a sphere given its surface area, you can use the following formula:
Surface Area of a sphere = 4πr²
Where r is the radius of the sphere.
Given that the surface area is 7.84π ft², we can equate it to the formula:
7.84π = 4πr²
Now, divide both sides of the equation by 4π:
7.84π / (4π) = r²
1.96 = r²
To find the value of r, take the square root of both sides:
√1.96 = √r²
1.4 = r
Therefore, the radius of the sphere is 1.4 feet.
