there are 9 plates and x slices on each plate so 9x
To get the radius we proceed as follows:
area=θ/360πr²
area=40 sq. units
θ=110°
thus the value of r will be:
40=110/360πr²
r²=40(110/360*π)
r²=41.66966
r=6.4552
Answer:
3
Step-by-step explanation:
The semicircle doesn't have any sides and the dotted lines are just there as an image for u.
Step-by-step Answer:
Two ways to find the answer.
1. Using sine rule, we have
d/sin(D) = f/sin(F) (d=EF, f=DE=3)
cross multiply and solve for d:
d=f*(sin(D)/sin(F) = 3*sin75/sin50 = 3.783.
2. using the theorem that if angle D is greater than angle F, then the length of the opposite side of D is also smaller than the opposite side of F.
Here D>F, so d>f. The only answer choice greater than 3 is 3.8, so there.
Answer:
D
Step-by-step explanation:
200 is the weight of the jar
110 is the weight of the contents
n is the number of jars.
The equation is for mass of an "n" number of jars
