V=3.14*4/3*r^3
r=4/2=2
v=3.14*4/3*2^3=33.4933333
B
The number 41 has a prime factorization of 1 × 41. The only numbers that divide into 41 evenly are 1 and 41. Therefore, 41 is a prime number.
Answer:
x = 3,0 y = 0, -4
Step-by-step explanation:
Let the arc is ABC with angle 324 degree, to find the length of that arc follow the steps;
The circumference of the circle E is :C = 2 r π
C = 2 * 40 π = 80 π cm.
Also 324° / 360° = 0.9m Arc (ABC ) = 0.9 * 80 π = 72 π cm
There is also formula for calculating the measure of an arc:
m Arc = r π α / 180°
m Arc = 40 π * 324 / 180
= 40π * 1.8 = 72 π
Now we have to find the exact length ( π ≈ 3.14 )
m Arc ( ABC ) = 72 * 3.14 = 226.08 cm
