expeople1 [14]

Formula for surface area of a sphere of radius r is A = 4pi*r^2.

The same formula, for the case where the radius is 2.45 times greater, comes out to A = 4pi*[2.45r]^2.

Just find the ratio of

4pi*r^2 to 4pi*[2.45r]^2. It is 1/6.

How do you find "a" in -10+a=6a-7a please help I do not know how to find what the answer is.

Sunny_sXe [5.5K]

-10 + a = 6a - 7a

Rearrange the left hand side

a - 10 = 6a - 7a

Simplify 6a - 7a

a - 10 = -a

Add a on both sides

2a - 10 = 0

Add 10 on both sides

2a = 10

Divide by 2 on both sides

a = 5
