Answer:

280 m

Step-by-step explanation:

a² + b² = c²

450² + b² = 530²

202,500 + b² = 280,900

280,900 - 202,500 = 78,400

√78,400 = 280

Find the surface area of the cylinder give your answer in terms of pi. The radius is 4mm and the height is 5mm
Komok [63]
The surface area of a cylinder is the area of the bases plus the area of the side, or SA = 2*A₁ + A₂

Since the area of a circle is \pi r^{2},
SA = 2*(\pi r^{2}) + A₂

Since the area of the side is height * the circumference of the circle or A₂ = h * 2 \pi r, then SA must be;

SA = 2* \pi (r ^{2} )+h*2 \pi r
SA = 2* \pi (4 ^{2} )+5*2 \pi (4)
SA = 32* \pi+80 \pi
SA ≈ <span>351.858377202</span>
