Answer:
V= volume of cone A=Ah A= πr2
A= area of base 3
H= height
V= (3.1416)(16)(15) 3.1416x16x15= 753.9
3
V= 753.9 753.9÷3= 251.3 cu. in
3
Volume of the cone is 251.3 cu. in
I hope this helps you. Good luck!
Here's one shortcut:
2.3×10^9=1000(2.3×10^6) because your adding 3 more zeros to 2300000
Answer:
Step-by-step explanation:
Let the speed of the car be "X". From 3 am until 1 pm (10 hours), the car will travel 10*X miles.
The speed of the airplane is (X +200). From 11 am until 1 pm (2 hours), the plane will travel 2*(X+200).
The distance travelled is the same, so:
10*X = 2*(x+200)= 2x+400
Subtract 2*X from both sides:
8*X = 400
X = 400/8 = 50 mph.
IN the given figure.
angle A + angle B + angle C = 180°
( angle sum property of Δ)
58°+47°+ x = 180°
105°+ x =180°
x = 180° - 105°
<h3>x = 75°</h3>
thus correct option is (d)
hope this will help u!!
