To estimate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.

<h3>What is a cylinder?</h3>

In mathematics, a cylinder exists as a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases exist normally circular (like a circle) and the center of the two bases exists joined by a line segment, which exists named the axis.

A cylinder exists as a closed solid that contains two parallel circular bases joined by a curved surface.

To calculate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.

The diameter of a circle is 11 m. Find its area to the nearest tenth.
aliya0001 [1]

Answer:

95.0 m²

Step-by-step explanation:

The formula for the area of a circle of radius r is A = πr².

Here the diameter is given and is 11 m; therefore the radius is r = (11/2) m.

Thus, the area of this circle is

A = πr² = π(11/2 m)²  = π(121/4) m², or approx. 95.0 m²

Find the radius of a circle given that a central angle of measure pi/4 intercepts an arc of length 1.5in
soldi70 [24.7K]

Given:

Central angle = \dfrac{\pi}{4}

Arc length = 1.5 in

To find:

The radius of the circle.

Solution:

We know that the formula for arc length is

s=r\theta

Where r is radius and \theta is the central angle in radian.

Substitute the given values in the above formula.

1.5=r\times \dfrac{\pi}{4}

6=\pi r

\dfrac{6}{\pi}=r

\dfrac{6}{3.14}=r

On further simplifiation, we get

r=1.910828

r\approx 1.91

Therefore, the radius of the circle is 1.91 in.
