Hamburgers cost $3 and hotdogs cost $2 the total cost of buying b hamburgers and d hotdogs can be expressed by c=3b+2d. how can this equation be solved for d

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!

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
