Answer:
C.
Step-by-step explanation:
First finding height using Pythagoras theorem
(H)²=(B)²+(P)²
8.2²=5.4²+P²
P² = 67.24 - 29.16
P² = 38.08
P = 6.2
Now
Volume of cone = (1/3)πr²h
= (1/3)(3.14)(5.4)²(6.2)
= (1/3)(567.9)
= 189.2 cm³
Answer:
0.25
Step-by-step explanation:
11/12 = 0.917
2/3 = 0.667
0.917 - 0.667 = 0.25
Answer:
C
Step-by-step explanation:
First of all their is an easier way solving this 2l/ + l^2
but how you need it is c because the base is 100 and each face is 40 how 10x8=80 80/2=40
It is d i did the test and got an a
One car travels at a speed of 75 kilometers per hour and the other car travels at a speed of 105 kilometers per hour.
Since both the cars are travelling towards each other their combined speed will be: 75+105=180 km/h.
Now, since the distance between the cars to start with is 540 km. Therefore, the time taken before the cars collide is:
hours.
Now, the speed of the canary is 100 km/h.
Therefore, the Canary flies flies for (100 km/h)x(3 hours) = 300 km before the cars collide.
