oksian1 [2.3K]

Answer: <em><u>C. the base period amount.</u></em>

<u><em>Explanation: </em></u>While implementing a horizontal analysis on a given income statement, we compute a percentage change in any individual item by dividing the dollar amount of change from base to current  time period with <u><em>the base period amount.</em></u>

i.e. % Change in Individual item = \frac{Current\ Dollar\ - Base\ Dollar }{Base \ period \ amount}

Find the volume of a right circular cone that has a height of 12.2 cm and a base with a circumference of 18.5 cm. Round your ans
loris [4]

Answer:

110.7 cm³ to the nearest tenth

Step-by-step explanation:

The volume V of a cone whose circular base has a radius r and a height h is given as

V = 1/3 πr²h

where π = 22/7

Given the circumference of the circular base as 18.5cm, we must find the radius before we can computed the volume. The relationship between the radius and the circumference is such that the circumference C

= 2πr

hence,

r = C/2π

= 18.5/2π

since the height of the cone is 12.2 cm, the volume V

= 1/3 * π * (18.5/2π)² * 12.2

= 110.71 cm³

A concrete patio is 5 2/3 feet wide. And has an area of 36 5/6 square feet. Is the concrete slab long enough to fit a 7 foot pic
matrenka [14]

No.

We know the width is not long enough to lay the picnic table across, as it is only 5 2/3 ft. wide. We can see if the other side is long enough by dividing the product of the two sides by the side we know.

36 5/6 divided by 5 2/3 = 6 1/2 ft. which is not long enough to house a 7 ft. long picnic table without going diagonal.
