Answer:
A≈926.54
Step-by-step explanation:
π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr, where r denotes the radius of the base of the cone, and L denotes the slant height of the cone.Using the formulas
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·9·(9+222+92)≈926.54225
The length of the rectangle is 25cm and the width of the rectangle is 45cm and this can be determine by forming the linear equations.
Given :
Let 'a' be the length of the rectangle and 'b' be the width of the rectangle. Than the perimrter of the rectangle will be:
a + b = 70 ---- (1)
Now, the area of the rectangle will be:
a = 25
Now, put the value of 'a' in equation (1).
b = 70 - 25 = 45
b = 45
Therefore, the length of the rectangle is 25cm and the width of the rectangle is 45cm.
