You do
6 over 7 multipled by three.
You multiply 6 and 3= 18
7x1=7
18/7 is the answer
or 2 4/7
Answer:
h = 21 unit ;
Volume = 630 unit³
Step-by-step explanation:
Given that :
Base area, B = 6 units²
Volume = 63 units³
Volume of triangular prism :
63 = 1/2 * base area * height
63 = 0.5 * 6 * h
63 = 3h
h = 63/3
h = 21 m
Volume of pentagonal prism :
V = 1/2(5 * side * apothem) * height
(1/2 * 5 * 6 * 2) * 21
(5 * 3 * 2 * 21)
= 630 unit³
i think it might be 3 53/100

Divide -8 on both sides while flipping the sign from "greater than" to "less than".
Final Answer: s< -2</span>
Answer:
if exterior angle is 10 degrees, then interior angle is 180 -10 = 170 deg.
Each trinaglke inside the polygon will be isosceles with two angles of 170/2 - 85 degrees each.
So, angle at centre = 180 -170 = 10 deg.
Ttal angle at centre = 360 deg.
No of sides = 360 /10 = 36 sided polygon.
b) Sum of interior angles is given by (2N-4) Right angles
So: 9900 = (2N-4)x90 = 180N - 360
180N = 9900 +360 = 10260
N = number of sides = 10260 / 180 = 57 sides
