The volume of a hemisphere is 2/3 pi R^3.
1) 2/3 x 3.14 x 10^3
2)2/3 x 3.14 x 1000
3)2/3 x 3140
4) 2093.3
First, find the fraction of the circumference represented by central angle 7pi/8:
7pi/8
--------
2pi
Then find the circumference; it is C = 2 pi r, or 2pi(6), or 12 pi units
Then the arc length is 7pi/8 7
-------- * 12 pi = -------- units, or 21/4 units, or 5 1/4 units.
2pi 16 pi
2/5
because if you turn 3 1/5 into an improper fraction that 16/5 divided by 8/1 equals 16/40 which when simplified equals 2/5
Answer:
600.4 cm^2
Step-by-step explanation:
first we should find the base of samller triangle
hypotenuse = 35 cm
one side = 30 cm whereas other has be be find
using pythagoras theorem
a^2 + b^2 = c^2
30^2 + b^2 = 35^2
900 + b^2 = 1225
b^2 = 1225 - 900
b^2 = 325
b = 
b = 
area of big triangle
base = 22 + 
area of a triangle = base * height / 2
= 30 (22 +
) /2
=30*22 + 30*
/ 2
=660 + 540.83 / 2
=1200.83 / 2
=600.415
=600.4 cm^2
