In triangle ABC find b to the nearest degree given a=7 b=10 and c is a right triangle
eimsori [14]

Answer:

∠B =55.00797173^{\circ}

Step-by-step explanation:

Given : a=7 b=10 and C is a right triangle

solution :

refer the attached figure .

Since ΔACB is right angled triangle so we will use trigonometric ratios .

tan\theta=\frac{perpendicular}{base}

Perpendicular = b =10

Base=a=7

Putting value in formula:

tanB=\frac{10}{7}

tanB=1.42857

B=tan^{-1}1.42857

B=55.00797173^{\circ}

Thus ∠B =55.00797173^{\circ}

A grain silo has a diameter of 4.4 meters. The height of its cylindrical portion is 6.2 meters.
erastova [34]
Volume of a cylinder = Height x base are
H = 6.2 m
Bae are = π.R² ; Diameter =4.4 m, then Radius = 2.2 m
Base area = π(2.2)²
And Volume=:
V= (6.2).(π,2.2²) = (6.2).(π)(.4.84) = 30.008.π ≈ 94.2 m³
