Find the surface area and round to the nearest hundredths place when necessary.
pashok25 [27]

Answer:

First lets find the area of the bottom circle:

7.2 is your radius so:

7.2^2 = 51.84 the reason why you square your radius is because thats apart of the formula when finding the are of a circle.

lets continue:

51.84 x 3.14(pi) = 162.7776

Now we need to find the area of the round surface but first we need to find the circumference of one circle and multiply it by the height.

2 x 3.14 x 7.2 = 45.216

Now lets multiply it by the height:

45.216 x 17 = 768.672

Now lets add both areas:

768.672 + 162.7776 = 931.4496 dont forget to round to the nearest hundredths place! 931.4496 rounded up = 931.45 square meters is your answer.

The roof of one building is 400 feet below the roof of another building. A person standing on the lower roof sees another person
m_a_m_a [10]

The distance between the two buildings is 844.23 feet apart, we go this answer by simply applying the SOH CAH TOA method

<h3>Trigonometry</h3>

Given Data

  • Height of Building A (Opp) = 400 feet
  • Angle of Elevation θ = 35°
  • Distance between the buildings Adj = ??

Applying the SOH CAH TOA Approach we have

Tan  θ = Opp/Adj

Substituting our given data we have

Tan 35 = 400/x

0.4738 = 400/x

make x subject of the formula we have

x = 400/0.4738

x = 844.23 feet
