54 miles
using the formula
speed = 
= 
= 12 mph
continuing at 12 mph then
distance = speed × time = 12 × 4.5 = 54 miles
Answer:
surface area=2816 m² & volume =205.33m³
Step-by-step explanation:
here
diameter of base (d) -28 m
radius(r) = d/2=14 m
vertical height of cone (h)-48 m
slant height of cone (l)-50 m
surface area (TSA)-?
volume (v)-?
we know
TSA=(pie*r*l)+pie*r*r
=pie*r(l+r)
=22/7* 14(50+14)
=22*2(64)
=22*128
=2816 m²
again
v=1/3 pie*r*r
=1/3*22/7*14*14
=1/3*22*2*14
=205.33 m³
Answer:
5 1/3 inches
Step-by-step explanation:
R=3
Vcyl.=36(9π)=324π
Vcone=4(9π)=36π
V pencil=324π+36π=360π
If (3)
x+y
=81 and (81)
x−y
=3, then the values of x and y are 17/8 and 15/8
