Answer:
A
Step-by-step explanation:
A is a parabola
Answer:
989cm
Step-by-step explanation:
103, 131, 149, 111
Bottom length = 103 + 149 = 253
Left height = 131 + 111 = 242
103 + 131 + 149 + 111 + 253 + 242 = 989
Answer: Volume = 174.71 cubic meters
Step-by-step explanation:
Hi, to answer this, first, we have to apply the formula for the circumference (C) of a circle.
C= 2πr
Substituting with c=19.4 in the formula, and solving for the radius (r)
19.4= 2πr
19.4/ 2π =r
r= 3.09
Finally we apply the formula:
Volume of a right circular cone: 1/3 π r^2 h
Where h is the height of the cone and r is the radius of the base.
Replacing with the values given and calculated:
V=1/3 π (3.09)^2 (17.5)
V = 174.71 cubic meters
7/11 = 0.63 with a line over the 63 because it repeats = 63.6%
