Area of triangle = 24cm
Area of rectangle = 120
therefore, w x 12 = 120
w = 10
Half of the circumference:
18.84/2 which would leave you with 9.42 feet.
Answer:
Step-by-step explanation:
<u>27.</u> the sum of 2 complementary angles=90
8x-17+5x-10=90
13x=90+27
13x=117 <u>x=9 </u>
<u>28. </u> the sum of supplementary angles=180
17x-12+3x-48=180
20x=180+60
20x=240
<u>x=120</u>
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
