Answer:

101.1%

Step-by-step explanation:

The two batteries are in the shape of cylinder.

The total surface area of a cylinder

SA = (2πr^2 + 2πrh ) =

For AAA battery

h = 0.8mm

r = 1.9 mm

SA = (2π(1.9)^2 + 2π × 1.9 × 0.8 )

SA = 22.68 + 9.55

SA = 32.23 mm^2

For AA battery

h = 1 mm

r = 2.75 mm

SA = (2π(2.75)^2 + 2π×2.75× 1 )

SA = 47.52 + 17.28

SA = 64.80 mm^2

Increase in SA = 64.80 - 32.23

Increase in SA = 32.57

% increase = increase in SA/AAA × 100

% increase in SA = 32.57/32.23 × 100

% increase in SA = 101.1%

*Mastery Check. DO NOT ask for help. Find the area of the sector. Round your answer to the nearest tenth.
Juliette [100K]

The area of the sector is 472.6 ft²

<h3>Area of a Sector</h3>

For finding the area of the sector, you need apply the formula:

A=\pi r^2* \frac{\alpha }{360}, where:

r= radius

α= central angle

The question gives:

r= radius= 19 ft

α= central angle = 150°

Thus, the area of the sector will be:

A=\pi r^2* \frac{\alpha }{360}=\pi *19^2*\frac{150}{360} =472.6
