Answer:

154π cm²

Step-by-step explanation:

Radius (r) = 7 cm

Height (h) = 4 cm

Surface area of cylinder

= 2πr (h + r)

= 2π (7) (4 + 7)

= 2π (7) (11)

= 2π (77)

= 154π cm²

______

Answer:

<u>154π cm²</u>

Step-by-step explanation:

<u>Formula for the Surface Area of a Cylinder</u>

  • SA = 2πr (h + r)

<u>Solving</u>

  • Here r = 7 cm and h = 4 cm
  • SA = 2πr (h + r)
  • SA = 2π × 7 (7 + 4)
  • SA = 14π × 11
  • SA = <u>154π cm²</u>

Ella and jade both ran a marathone ella finished 4 hours 6 mins and 13 seconds jade finished in 4 hours and 3 mins and 18 second
spin [16.1K]

Answer:

Jade is faster than Ella by 2 minutes and 55 seconds.

Step-by-step explanation:

We are told that Ella and Jade both ran a marathon. Ella finished marathon in 4 hours 6 mins and 13 seconds. Jade finished marathon in 4 hours and 3 mins and 18 seconds.

We can write 4 hour 6 minutes 13 seconds as 4 hour 5 minutes 73 seconds. 1 minute has been borrowed to the seconds side, and seconds become 13+60 = 73 seconds.

We can see that Ella took more time than Jade. Let us find how much more time Ella took than Jade by subtracting time taken by Jade from time taken by Ella.  

4\text{ hr }5\text{ min }73\text{ sec }-4\text{ hr }3\text{ min }18{ sec }= 2\text{ min }55\text{ sec }  

We can see that Jade took 2 minute and 55 seconds less than Ella , therefore, Jade was faster than Ella by 2 minutes 55 seconds.

cupoosta [38]

Answer:

Ted will need 3\frac{3}{4} cups of pretzels to make 15 cups of trail mix.

Step-by-step explanation:

Ted is making trail mix for a party. He mixes 1 1/2 cups of nuts, 1/4 cup of raisins, and 1/4 cup of pretzels.

So, 1/4 cup of pretzels to make 1 trail mix

       x cups of pretzels to make 15 trail mix

Using the ratio and proportional

∴ x = (1/4) * 15 = 3.75 = 3\frac{3}{4} cups.

<u>Ted will need </u>3\frac{3}{4}<u> cups of pretzels to make 15 cups of trail mix.</u>

If P(A) = 1/2, P(B) = 0, then P(A Î B) is???
Ainat [17]
It is given that P(A) = 1/2 and P(B) = 0
P(A Î B) = P (A ∩ B) / P(B) = P (A ∩ B)/0

As zero is in the denominator, the expression can't be defined. 

In short, final answer is not defined.

Hope it helped.
