Area is determined by using the formula A=lw  Area= Length x  Width

A= 1 1/4 x 3   convert to an improper fraction

A= 5/4 x 3/1  multiply

A=15/4   divide

A=3 3/4 square feet

Answer: A=3\dfrac{3}{4}\ ft^2

Step-by-step explanation:

Given: The dimensions of the wrapping paper :

1\text{ and}\dfrac{1}{4}\text{ feet }\text{ by 3 feet}\\\\\text{i.e }1+\dfrac{1}{4}\text{ feet }\text{ by 3 feet}\\\\\text{i.e }\dfrac{5}{4}\text{ feet }\text{ by 3 feet}

Now, we know that the area of a rectangle is given by :-

A=length*width

Now, the area of the wrapping paper is given by :-

A=\dfrac{5}{4}\times3=\dfrac{15}{4}=3\dfrac{3}{4}\ ft^2

Ahat [919]

Answer:2355.31\ cm^3

Step-by-step explanation:

Given

diameter of the cone is  d=23\ cm\quad [r=\frac{d}{2}=11.5\ cm]

The height of the cone is  h=17\ cm

The volume of a cone is  V=\dfrac{1}{3}\pi r^2h

Insert the values

\Rightarrow V=\dfrac{1}{3}\times \dfrac{22}{7}\times 11.5^2\times 17=2355.309\\\\\Rightarrow V\approx 2355.31\ cm^3

Thus, the volume of the cone is 2355.31\ cm^3
