Answer:
Therefore the area of the screen cleared is 1414.28 cm².
Step-by-step explanation:
Given:
a windscreen wiper of a vehicle of length 30 cm
Consider this length as Radius of Semicircle, r = 30 cm
clears out an angle of 180 degrees implies Semicircle Shape
pie=22/7
To Find:
Area of the screen cleared
= ?
Solution:
We have
Substituting r and pie we get
Therefore the area of the screen cleared is 1414.28 cm².
Answer:
6 pounds 3 ounces
Step-by-step explanation:
16 oz in a lb. 16 *6 = 96. Leaving 3 oz left.
It would be more difficult to run up a slope of 5 because it would be steeper. with a 1/5 slope you would have a rise over run but with a slope of 5 it would just be all rise
Answer:
1. Slide over the Y-Axis
2. Reflection over the Y-Axis
3. Reflection over the y axis first as well as a rotation
Volume of a sphere formula is: V=4
/3 πr^3
You know v=17000 and pi=3.14
17 000 = 4/3 x 3.14 x r^3
(divide 17 000 by 4/3 x 3.14 ) --> r^3 = 4060.51 (2dp)
(cube root is to get just r) r = 15.95 inches (2dp)
There 15 inches to the nearest inch.
Hope this is correct! :D
