WORKSHEET-2

Margarita [4]

Answer:

1. $\frac{C}{D}$ = 3.143

2. Circumference

3. Area of the circle is 3850 $cm^{2}$ .

ii. Circumference of the circle is 220 cm.

Step-by-step explanation:

The area, A, and the circumference, c, of a circle can be determined respectively by:

A = $\pi$ $r^{2}$

C = 2 $\pi$ r

where r is the radius of the circle.

1. the ratio of the circumference and diameter, D, of a circle is:

r = $\frac{D}{2}$

so that,

C = 2 $\pi$ $\frac{D}{2}$

C = $\pi$ D

$\frac{C}{D}$ = $\pi$

= $\frac{22}{7}$

= 3.143

2. The distance around a circular region is known as it's circumference.

3. Given a circle of radius 35 cm, then:

A = $\pi$ $r^{2}$

= $\frac{22}{7}$ x $(35)^{2}$

= $\frac{22}{7}$ x 1225

= 22 x 175

A = 3850

Area of the circle is 3850 $cm^{2}$ .

C = 2 $\pi$ r

= 2 x $\frac{22}{7}$ x 35

= 2 x 22 x 5

= 220

C = 220 cm

Circumference of the circle is 220 cm.

If the volume of a rectangular pyramid is 150 inches cubes ,what is the volume of a prism with the same demensions

Ugo [173]

$\bf \stackrel{\textit{volume of a pyramid}}{V=\cfrac{Bh}{3}}\qquad \qquad \stackrel{\textit{volume of a rectangular prism}}{V=Bh}\qquad \begin{cases} B=base~area\\ h=height \end{cases}$

so let's notice, the volume of the rectangular prism is really 3 times as much of that of a pyramid with the same Base and Height.

so if the pyramid has a volume of 150, the prism will have volume of 3*150.
