The diagram shows a solid which is half of a cone. Calculate the total surface area of the solid.
Vilka [71]

Answer:

<h2>100πcm².</h2><h2>None of the options is correct</h2>

Step-by-step explanation:

Total surface area of a cone S = \pi r^{2}+\pi  rl\\

Since the diagram is half of a cone, its surface area will be S = \frac{\pi r^{2} +\pi rl}{2}

r = radius of the cone

l = slant height

From the diagram diameter of the cone = 16m;

r = 16/2 = 8m

l = 17m

S = \frac{\pi (8)^{2} +\pi (8)(17)}{2}\\S = \frac{64\pi + 136\pi }{2} \\S = 32\pi + 68\pi \\S = 100\pi cm^{2}

Find the surface area of the composite solid. Leave your answer in terms of pi.
bonufazy [111]
Total surface area = lateral area of cone + lateral area of cylinder + area of base of cylinder:
cone: πrL = π(5cm)(13cm) = 65πcm²
cylinder: 2πrh = 2π(5cm)(12cm) = 120πcm²
base: πr² = π(5cm)² = 25πcm²
total surface area = 65πcm² + 120πcm² + 25πcm² = 210πcm²

Is this question correct?
Andrews [41]

Answer:

10^20

3^11

3^24

10^12

Step-by-step explanation:

(10^2)^10=10^2*10=10^20

3^3*3^8=3^3+8=3^11

(3^3)^8=3^3*8=3^24

10^2*10^10=10^2+10=10^12
