C = 2<span>πr
so
r = C/2</span><span>π
r = 3</span>π/2<span>π
r = 3/2
r = 1.5
A = </span><span>πr^2
A = </span><span>π(1.5)^2
A = 2.25</span><span>π
answer
</span><span>2.25π in²</span>
Answer:
if the area is 7 then the total side length is sqrt 7. 2 is also sqrt 4 so x pretty much equals sqrt 3. this equation is a typo, as sqrt isn't a solution. moreover if you factor the square, it will equal x squared plus 4x plus 4.
Use a calculator and multiple
Answer:
Step-by-step explanation:
Given
The attached image
Solving (a): The area (one side up)
This is calculated as:
Area= Area of semicircle + Area of rectangle
So, we have:
Where:
--- the rectangle dimension
--- the diameter of the semicircle
So, we have:
Solving (b): Area when both leaves are up.
Simply multiply the area in (a) by 2
