A semicircle is a half of a circle.
Find the circumference of a full circle then divide in half.
Circumference = pi x r x 2
Circumference = 3.14 x 9 x 2 = 56.52
Semicircle = 56.52/2 = 28.26
21.4*pi(r^3)/3=1000 ,so use r from it to calculate SA=4*pi*(r^2)
don't ask me to do it completely unless u are unable to do it.
22.yes, 1:6
Answer:
It equals 1.66666666666...
But you can round it to 1.7 if your rounding to the nearest tenth.
Answer:
The correct option is y ≤1/3 x – 4
Step-by-step explanation:
If you look at the attached graph you will see that the inequality is the shaded area below the solid line.
The slope of the line is positive which is 1/3.
The y intercept is equal to -4
Thus the inequality must be:
y ≤1/3 x – 4
Therefore the correct option is:
y ≤1/3 x – 4 ....
Answer:
1/3 * 2/4 = 1/3 * 1/2 = (1*1)/(3*2) = 1/6
