Cylinder A has a radius of 6 feet and a height that is 5.5 feet less than Cylinder B. Cylinder B's radius is 4 feet. The cylinde

The height of cylinders A and B will be 11 feet and 16.5 feet.

<h3>What is the surface area of a right circular cylinder?</h3>

Let r be the radius and h be the height of the cylinder.

Then the surface area of the cylinder will be

SA = 2πrh square units

Cylinder A has a radius of 6 feet and a height that is 5.5 feet less than Cylinder B. Cylinder B's radius is 4 feet.

$\rm r_A = 6 \ feet\\\\\rm h_B = 5.5 + h_A \\\\ r_B = 4 \ feet$

The surface area of cylinder A will be

SA = 2π × 6 × $\rm h_A$

The surface area of cylinder B will be

SA = 2π × 4 × $\rm h_B$

The cylinders have the same surface area. Then we have

2π × 4 × $\rm h_B$ = 2π × 6 × $\rm h_A$

$\rm 4 (5.5 + h_A ) = 6 h_A \\\\2h_A = 22\\\\h_A = 11$

Then the height of the cylinder B will be

$\rm h_B = 5.5 + h_A \\\\h_B = 5.5 + 11\\\\h_B = 16.5$

The height of cylinders A and B will be 11 feet and 16.5 feet.

More about the surface area of the cylinder link is given below.

A carnival ride is in the shape of a wheel with a radius of 15 feet. The wheel has 24 cars attached to the center of the wheel.

Nataly_w [17]

Answer:

central angle = 360/24 = 15°

arc length = 15/360 * 2π * 15 = 1.25π = 3.93 feet.

Area of a sector = 15/360 * π * (15)^2 = 9.375π = 29.45 square feet

Hope This Helps! Have A Nice Day!!

24 1/4 - 15 1/2 I really need help with this

Mamont248 [21]

first, you must make the fractions have the Least Common Denominator, which in this case is 4. the new equation is 24 1/4 - 15 2/4. then you just subtract. the answer is <u>8 3/4</u>
