Determine the missing angle

Part a : solve -vp + 40 < 65 for v part b : solve 7w - 3r = 15 for r show your work .

Use the radius you found in part i (r=26.8 cm) with the surface area formula below to find the surface area of the sphere. show your work and round your answer to the nearest tenth. the surface area of a sphere: sa = 4πr^2 self note: 3.8.4

Find the equation using the point (4,8)
