Answer:

65°

Step-by-step explanation:

To obtain Angle A, we use the cosine rule ;

Cos A = (b² + c² - a²) / 2bc

Cos A = (12² + 14² - 14²) / 2(12)(14)

Cos A = 144 / 336

A = Cos^-1(144/336)

A = 64.62°

A = 65°

Mia is calculating the volume of the cylinder below using the following work. A cylinder with height of 47 meters and diameter o
inn [45]

Mia’s first error was " she forgot to multiply π by (17.5)²(47) "

Step-by-step explanation:

The formula of the volume of a cylinder is V = π r² h, where

  • r is the radius of the base of the cylinder
  • h is the height of the cylinder

∵ The diameter of the base of the cylinder is 35 meters

∵ The radius = \frac{1}{2} × diameter

∴ The radius = \frac{1}{2} × 35 = 17.5 meters

∴ r = 17.5

∵ The height of the cylinder = 47 meters

∴ h = 47

- Substitute r and h in the formula of the volume

∴ V = π (17.5)²(47)

∵ Mai's first step is V = (17.5)²(47)

- She forgot to put π

∴ Her first error is she forgot to multiply π by (17.5)²(47)

Mia’s first error was " she forgot to multiply π by (17.5)²(47) "
