Answer:
5^3
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
sinx=sin(π3−π)=−sin(π3)=−12.
cosx=cos(π3−π)=−cos(π3)=−√32.
tanx=−12−√32=1√3=√3.
cotx=1√3=√33.
secx=1cos=−2√3=−2√33.
cscx=1sin=−2.
Answer:
0.800 or 0.008
Step-by-step explanation:
The area of semi-circle is 8π cm² with diameter of 8cm.
What is area of semi-circle?
- The area that the semicircle occupies is that which is contained inside its perimeter. Half of a circle is a semicircle.
- The area of a semicircle will therefore be equal to half that of a circle. Both the radius and the diameter can be used to get the semicircle's area.
- The formula used to determine a semicircle's area in terms of radius "r" is written as follows:
Area of circle = πr²/2
- Area of semi-circle= πd²/8 is the formula used to determine a semicircle's area in terms of its diameter.
- The value of the constant is 22/7, or 3.14.
Given:
Diameter = 8cm
Area of semicircle = πd² / 8
=π8² / 8
= 8π cm²
Hence, the area of semi-circle is 8π cm².
