Answer:
67.5 ft^2
Step-by-step explanation:
First find the area of the circle.
A = pi r^2
A = pi (8)^2
A = 64pi
There are 360 degrees in a circle
The shaded area has 121 degrees
The fraction is 121/360
The fraction shaded is 121/360
The fraction of the circle is the same as the area
121/360 A = 121/360 * 64 pi
area shaded = 67.54488889
To the nearest tenth
area shaded = 67.5
Answer:
d) 405 = 15 times 4.5 times h
The height of the prism 'h' = 6 inches
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given Volume of prism
V = 405 cubic inches
<em>Given length of the prism </em>
<em> L = 15 inches</em>
<em>Given width of the prism</em>
<em> W = 4.5 inches </em>
<em>The volume of the prism </em>
<em> V = l w h</em>
405 = 15 ×4.5× h
405 = 67.5 h
Dividing '67.5' on both sides , we get
h = 6 inches
<u>Final answer:-</u>
The height of the prism 'h' = 6 inches
Answer:
15
Step-by-step explanation:
the triangles are similar so will be the same proprotion,
