The math club is doing a fundraiser to raise money to attend a math competition. the club was told by their advisor to raise $2000, but they decided to raise $4000. the club is selling " i like tt" t-shirts for $10 and "i like tt" sweaters for $20. let x equal the number of t-shirts sold and let y equal the number of sweatshirts sold.
write a linear equation to represent raising $4000

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
