I should think that this works just like the trapezoids
volume=base times height
so
base=pir^2
height=x
r=d/2=14/2=7
base=pi7^2=49pi
so
V=49pix
1176pi=49pix
divide both sides by 49pi
24=x
I would say 24 units
Answer:
3. 9
4. 24
Step-by-step explanation:
3. 15.5/3.1 = 5 45/5 = 9
4. 3r = 16p 128p = ?r
128/16 = 8x3 = 24
r = ref
p = player
/ = divide
Well, first since i split this up into 3 shapes. Then I multiplied 4x8 which was 32 and since there were two,it would be another 32. Then I multiplied 12x4 which was 48. Then I added 32+32+48 which equaled 112 square feet.
K, so
first one, ok, all of them are prime, 5 and 7 and 13 are all prime
2nd one, 24 is not prime
3rd one, 3 and 13 are prime
4th one, 4 is not prime
answe is 1st and 3rd one
