Answer:
10000 (1sf)
12000(2sf)
11900(3sf)
11940(4sf)
Step-by-step explanation:
I would go for 12000 (2sf) if it the degree of accuracy isn't specified in the question
The formula for the volume of a cone, V, is:
V = [1/3] * π * (radius)^2 * height
Here radius = 6 feet / 2 = 3 feet
Height = 15 feet
V = [1/3] π (3 feet)^2 * 15 feet = 45π feet^3
Answer: 45π feet^3
Answer:
Option a) circle 5 meters and 22 meters
Step-by-step explanation:
We are given the following information in the question:
A pair of diameter and the circumference is given. We have to find a correct approximations for the diameter and circumference.
a) circle 5 meters and 22 meters

b) 19 inches and 50 inches

c) 33 centimeters and 80 centimeters

Thus, no pair gives a reasonable approximation. Only the circle with diameter 5 and circumference 22 meters have closest approximation.

Answer:
-256 +64 - 16 + 4 - 1
Step-by-step explanation:
A series is the summation of all the terms in a sequence.
So it is only the last three options that qualify to be a series.
The series 2 +5 + 8 + 11 + 14 + 17 has no common ratio. It is not geometric.
The series 1+1+2+3+5+ 8 +13 +21 also has no common ratio. It is not geometric.
The series -256 +64 - 16 + 4 - 1 has a common ratio of

There the only series that is geometric is.
-256 +64 - 16 + 4 - 1
