When writing a number in scientific notation the first factor must have a value greater than or equal to one but less than 10.
Answer:
Volume of cone = 209.44 cm²
Curved surface area of cone = 188.57 cm
Step-by-step explanation:
Given:
Height h = 8 cm
Slant height l = 10 cm
Radius r = 6 cm
Find:
Volume of cone
Curved surface area of cone
Computation:
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)π(5)²(8)
Volume of cone = 209.44 cm²
Curved surface area of cone = πrl
Curved surface area of cone = π(6)(10)
Curved surface area of cone = 188.57 cm
To find the mean, you add up all the numbers and divide by the number of numbers in the sequence
28+42+56+70+84+98+112
=490 divide by 7
=70
