Answer:
V = 3533
Step-by-step explanation:
Volume of a cylinder is given by
V = pi r^2 h
Using 3.14 for pi
V = (3.14) (7.5)^2 * 20
V = 3532.5
To the nearest whole number
V = 3533
Answer:
16.0"
Step-by-step explanation:
ASSUME the pyramid is a square right pyramid.
height = 15"
base side length = 11"
(Following edited/corrected thanks to cwrw238)
Slant height
= sqrt(5.5²+15²) using Pythagoras theorem
= sqrt(255.25)
= 15.98"
Answer:
-3 < x ≤ -1
Step-by-step explanation:
-8 < 5x + 7 ≤ 2
First, subtract 7 from all sides of the inequality:
-8 - 7 < 5x + 7 - 7 ≤ 2 - 7
-15 < 5x < -5
Divide all sides by 5 to isolate x:
-15 ÷ 5 < 5x ÷ 5 ≤ -5 ÷4
-3 < x ≤ -1
