Answer:
. Multiply 15 by 1, then divide by 5
Area of square = 24cm²
⇒ Length = √24
Find the diagonal of half the square:
a² + b² = c²
c² = (0.5√24)² + (√24)²
c² = 6 + 24
c² = 30
c = √30
The diagonal of half of the square is the radius of the circle.
⇒ radius = √30
Area of the semicircle = 1/2πr² = 1/2π(√30)² =15π
Answer: 15π²
Answer:
9/4
Step-by-step explanation:
First multiply denominator by the whole
That is: 4 x 2 = 8
Secondly, whatever answer you got add it to the numerator
That is: 8 + 1 = 9
Lastly, whatever answer you got, take that as the numerator and the denominator remains the same
That is: 9/4
Finally, this is your improper fraction of the number provided!
Hope it helps!!!
Answer:
Step-by-step explanation:
The formula of volume of cone is
V=\frac{1}{3}\pi r^{2} h
where, r is the radius
we have given diameter = 12 =2r
r=6 ft
h is the height h=6 ft
\pi =3.14
Substitute the value in the formula,
V=\frac{1}{3}\pi r^{2} h
V=\frac{1}{3}\times (3.14)\times 6^{2}\times 6
V=\frac{1}{3}\times 3.14\times 36\times 6
V=226.08 ft^3
Therefore, The volume of cone is 226.08 cubic ft.
