Answer:

1473 in²

Step-by-step explanation:

<u>Surface area, including sides and the top lid:</u>

S = πr² + 2πrh
S = 3.14*7² + 2*3.14*7*30 = 1472.66 in² ≈ 1473 in² (rounded)

Answer:

Just substitute the values in!
(-5/9) + (-4/3) - 2/3 = - 5/9 - 12/9 - 6/9 = -23/9.

If the measure of arc AD is 65 degrees and the measure of arc BC is 45 degrees, what is the measure of angle BEC?

krek1111 [17]

Answer:

$\angle BEC=55 \textdegree)$

Step-by-step explanation:

From the question we are told that:

Arc $AD =65 \textdegree$

Arc $BC =45 \textdegree$

Given The angle of intersecting chords theorem

Generally the equation for angle BEC is mathematically given by

$\angle BEC=\frac{1}{2} (\angle of arc AD+\angle of arc BC)$

$\angle BEC=\frac{1}{2} (65 \textdegree+45 \textdegree)$

$\angle BEC=55 \textdegree)$

Trigonometry!!!! find y round to the nearest tenth!

LekaFEV [45]

Answer:

Step-by-step explanation:

We can use Tan 27° to find the missing side (in this case, the opposite side to the angle measuring 27°)

Tan A = (opposite side)/(adjacent side)

Tan 27° = y/350

solve for y

350(Tan 27°) = y

178.3 = y (rounded to the nearest tenth)
