Answer:
-1/10
Step-by-step explanation:
since

u cross multiply
get -6=60k
=> k = -1/10
Answer:
121.5
Step-by-step explanation:
Area is bases times height. The height is 4.5. And the bases is double the height. So 4.5 times 2 is 27. so we back to area wich is now 4.5 times 27 which is 121.5
<h2>A = b times h </h2><h2 /><h2>h times 2 = b </h2><h2 />
V<span>=(</span><span>4/</span><span>3)</span><span>πr^</span><span>3
R=radius
Diameter= 2 times R
so,
R=7 ft
plugging the values;
V=(4/3)(3.14)(7)^3
V=1436.02 Cubic feet</span>
Answer:
247.21
Step-by-step explanation:
equation for height : c= a2 + b2
4.82 + 9.32
≈10.46566
equation for surface area: A=5
/4tan(54°)a2+5a
/2h2+(atan(54°)
/2)2
5
/4·tan(54°)·72+5·7
/2·7.972+(7·tan(54°)
/2)2
≈247.21018
round to nearest hundredth: 247.21
