Answer:
-0.8, 7/9, √3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Base is an equilateral triangle
slant hight= 12 in
side of base= 5 in
so, perimeter of base = 3(5)=15 in
lateral area = 1/2 pl =1/2 (15)(12) in
=90 in²

Your answer would be: <em>693.</em>
Explanation:
When finding the area in a problem use <em>L×W×H</em>.
That being said, you now have to multiply the <em>L×W×H</em> (7x9x11)
7 × 9 × 11 = <em>693</em>
So the answer would be <em>693</em> because, if you are finding an area you use <em>L×W×H</em> to find your area.
Answer:
a) 11%
b) 56%
Step-by-step explanation:
a) A= πr^2 6^2π= 36π A= 18^2π = 324π
36π/324π = .111111111111111111111111 or 11%
remember to cancel out the pi symbols when you are showing your work
(put a line across the pi symbols when dividing)
b) A= πr^2 18^2 π = 324π
A= πr^2 12^2π = 144π
324 – 144 = 180
180π/324π = .5555555555555555555555556 or 56%
