PLEASE HURRY!!!! TIMED!!!! WILL GIVE BRAINLIEST!!!!
sweet-ann [11.9K]

Answer:

\sqrt{28}

Step-by-step explanation:

You don't need to memorize all of the square roots.  Looking at each square root, find a number close to it that you know -- The square root of five is close to the square root of four, which is 2. The square root of 28 is close to the square root of 25, which is 5.  28 is a slightly bigger than 25, so the square root will be slightly greater than 5.

Please help! i don't know what to do, my formulas are not working for me. If anyone could please help i would really appreciate
Burka [1]

Answer:

  • The radius is r = 3 in,
  • The height is h = 4 in

<u>The area of the base:</u>

  • A(b) = πr² = π(3²) = 9π in²

<u>The circumference of the base:</u>

  • C = 2πr = 2π(3) = 6π in

<u>The area of the lateral surface:</u>

  • A(l) = Ch = 6π(4) = 24π in²

<u>The surface area:</u>

  • S = 2A(b) + A(l) = 2*9π + 24π = 42π in²

Ber [7]

Answer:

Step-by-step explanation:

first runs n+1 laps

and second runs n laps in the same time.

so (n+1)8=10n

10n=8n+8

10n-8n=8

2n=8

n=8/2=4

one lap=1 mile

4 laps=4 miles

4+1=5 laps=5 miles.

first runs 5 miles whereas second runs=4 miles.
