Answer 10

First, we need to convert the height and radius to the same units. Let's convert the radius to feet:

22 in = 22/12 ft = 1.8333 ft (rounded to four decimal places)

Now we can use the formula for the volume of a right circular cylinder:

V = πr^2h

where V is the volume, r is the radius, and h is the height.

Plugging in the values we have:

V = π(1.8333)^2(1.1)

V ≈ 11.845 cubic feet

To convert cubic feet to cubic inches, we need to multiply by (12 inches/1 foot)^3 to get:

V = 11.845 x (12)^3 cubic inches

V ≈ 2,561.4 cubic inches (rounded to the nearest tenth)

Therefore, the volume of the tree stump in cubic inches is approximately 2,561.4 cubic inches.

Answer 11

First, let's convert the radius to feet:

6 in = 6/12 ft = 0.5 ft

Now we can use the formula for the volume of a right circular cylinder:

V = πr^2h

where V is the volume, r is the radius, and h is the height.

Plugging in the values we have:

V = π(0.5)^2(1.3)

V ≈ 0.845 cubic feet

To convert cubic feet to cubic inches, we need to multiply by (12 inches/1 foot)^3 to get:

V = 0.845 x (12)^3 cubic inches

V ≈ 1,454.1 cubic inches (rounded to the nearest tenth)

Therefore, the volume of the tree stump in cubic inches is approximately 1,454.1 cubic inches.

Answer 12

The circumference of a circle is found by multiplying the diameter by π (pi), which is approximately 3.14159.

So, if the diameter of the circle is 13 inches, then the circumference is:

C = πd
C = 3.14159 x 13
C ≈ 40.8407

Rounding this to one decimal place gives:

C ≈ 40.8

Therefore, the circumference of the circle, to the nearest tenth, is approximately 40.8 inches.

Answer 13

We know that the circumference of a circle can be found using the formula:

C = πd

where C is the circumference and d is the diameter.

In this case, we are given that the circumference is 14π meters. So, we can set up the equation as:

14π = πd

To solve for d, we can divide both sides by π:

14π/π = d

Simplifying the left side gives:

14 = d

Therefore, the diameter of the circle is 14 meters.

Answer 14

The formula for the area of a circle is:

A = πr^2

where A is the area and r is the radius.

Given that the radius is 6 cm, we can plug this value into the formula and simplify:

A = π(6)^2
A = π(36)
A ≈ 113.1

Rounding this to the nearest whole number gives:

A ≈ 113

Therefore, the area of the circle, to the nearest whole number, is approximately 113 square centimeters.

Answer 15

We can start by finding the area of the rectangle and the area of the half-circle separately and then adding them together to get the total area.

The area of the rectangle is:

A_rect = L x W

where L is the length and W is the width. In this case, the rectangle has a length of 10 cm and a width of 6 cm, so we can plug these values into the formula:

A_rect = 10 cm x 6 cm = 60 square cm

The area of the half-circle is:

A_hc = (1/2) x π x r^2

where r is the radius of the circle. In this figure, the radius is 4 cm, so we can plug this value into the formula:

A_hc = (1/2) x π x (4 cm)^2

A_hc ≈ 25.13 square cm

To get the area of the entire figure, we add the area of the rectangle and the area of the half-circle:

A_total = A_rect + A_hc

A_total = 60 square cm + 25.13 square cm

A_total ≈ 85.13 square cm

Rounding to the nearest tenth gives:

A_total ≈ 85.1 square cm

Therefore, the area of the figure, rounded to the nearest tenth, is approximately 85.1 square centimeters.
