The surface area of a sphere is 196 π . Its radius is

The radius of the sphere is 7 units

Step-by-step explanation:

Surface Area

Given a sphere of a radius (r), the surface area is given by the formula:

If the surface area is given, we can solve for r:

The surface area of a sphere is given A=196π.

Calculating the radius:

r = 7 units

The radius of the sphere is 7 units

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
