Find the volume of the following cone. Use 3.14 for π.A. 9847.04 cubic meters

B. 39388.16 cubic meters

C. 10257.33 cubic meters

D. 41029.33 cubic meters

Answer 1

Answer:

Answer: A. 9847.04 cubic meters

Step-by-step explanation:

From the given picture, we have

The diameter of the cone = 28 m

Then the radius of the cone = $(28)/(2)=14\text{ m}$

Height of the cone = 48 inches

The volume of cone is given by :-

$V=(1)/(3)\pi r^2h\n\n\Rightarrow V=(1)/(3)(3.14)(14)^2(48)\n\n\Rightarrow V=9847.04\text{ m}^3$

Hence, the volume of the cone = $9847.04\text{ m}^3$

Answer 2

Answer:

Answer:

Step-by-step explanation:

Radius

= 28 ÷ 2

= 14 m

Volume

= 1/3 (3.14) (14)²(48)

= 1/3 (3.14) (196)(48)

= 9847.04 m³

Answer: 81.85 km/hr

Converting m/sec into km/hr, 25 m/sec = 90 km/hr

Average =

Time = 50/90 = 5/9 hr

next 120 km at an average speed of 80km/h

=> Time = 120/80 = 3/2 hr

last part of its journey at an average speed of 90km/h in 35 Minutes

time = 35 minutes = 35/60 hr = 7/12 hr

Distance covered = 90 * 7 /12 = 105/2 km

Total Distance = 50 + 120 + 105/2 = 435/2 km

Total time = 5/9 + 3/2 + 7/12 = ( 20 + 54 + 21) /36 = 95/36

Average speed = (435/2)/(95 /36) = 432 * 18 /95 = 81.85 km/hr

What is a 2c − 5b − c a − b simplified?

Answers

All you have to do is combine like terms. 2c and (-c) are like terms (-5b) and (-b) are like terms and a is a term. So, 2c combined with (-c) is C. (-5b) and (-b) combined is (-6b). Since a doesnt need to be combined with anything, you leave it as it is so your answer will then be c - 6b + a (this is the answer assuming that there is a + in front of the a. If there is a - sign, then just change your +a to -a at the end
