the surface area of the cylinder is 0.5mm
<span>(7y2 + 6xy) – (–2xy + 3)
7y^2 + 6xy +2xy +3
7y^2 +8xy +3
8xy + 7y^2 +3</span>
Step-by-step explanation:
Proof: equidistance means at an equal distance from two points
so: Take the distance formula and then plug the values in and compare.
Surface area of a sphere = 4πr² = 4π(15)² = 900π m²
Surface area of a sphere = 4πr² = 4π(10)² = 400π m²
7 because 3 times 7 is equals 21
