First work out the surface area of the solid
Area of cylindrical part:-
length of this part = 108 - 2*18 = 72 so its area
= 2 * pi * r * 72
= 2 *pi* 18 * 72 = 8143.01 cm^2
Area of the 2 hemispheres = 4 pi * 18^2 = 4071.50 cm^2
Total surface area of the solid = 12,214.51 cm^2
Cost of polishing = 12,214.51 * 7 = 85,501.58 paise
Answer:
-6 4/5
Step-by-step explanation:
Answer:
7.2(option 3)
Step-by-step explanation:
Use distance formula
√ (x2 − x1)² + (y2 − y1)²
√(6-2)²+(9-3)²
√(4)²+(6)²
√16+36
√52
7.2
(2,0) is the correct answer
Answer:
a) 8²
b) 2⁴ and 5⁴
Step-by-step explanation:
The power of a number is the base together with the exponent of the number.
The given expresion is
We can rewrite this as:
Over here the power being multiplied is
Also, the powers being multiplied in
are 2⁴ and 5⁴
