<u>Answer:
</u>
Volume of right circular cone is 18.6 cubic feet.
<u>Solution:
</u>
We need to find volume of right circular cone
Given height of right circular cone = 4.5 feet
Given circumference of base of the cone = 12.5 feet
Formula for volume of circular cone =
Where h is height and r is radius of base.
In given information we have height, but do not have radius. So first need to calculate radius of the base from given circumference of base.
Circumference of circle =
Given that circumference =12.5 feet
On substituting given value of height and calculated value of radius in formula of volume of cone , we get
Hence volume of right circular cone in consideration is 18.6 cubic feet.
Step-by-step explanation:
By quadrant I presume you mean 1/4 of the circle. The perimeter will be 1/4 of the circle’s circumference plus the length of the two radii that complete the 1/4 section.
C=2 × pi × r = 28 pi
Perimeter = 28 pi +14+14. using 22/7 for pi
22/7 × 28 +28 = 88 + 28 = 116
116 cm is perimeter
Hope my answer will be correct
If diameter is 2, radius is 1
Area of circle = πr^2 so π x 1^2
Answer = π
