Answer:
v=50
Step-by-step explanation:
use the formula V=A(h/3), where V is the volume and A is the area of the base. a=5 h=6 5×6=30 5×3=15 30+15=45 45 rounded to neared whole number which is 50
Area of shaded part = area of circle - area of the square
= pi (6)^2 - area of the square.
Area of square = (m of one side) ^2
measure of of side is found as follows:-
6^2 = 2s^2 where m of the side = 2s
s = sqrt 18 so side of square = 2 sqrt18
area of square = (2 sqrt18)^2 = 4*18 = 72
area of shaded region = 36pi - 72 = 41.1 sq units to neraest tenth
Step-by-step explanation:
b=1/2hr
2hr × b = 1
2hrb = 1
to find h divide both sides by 2rb
h = 1/2rb
