Answer:
Radius = 8.575 cm
Step-by-step explanation:
Formula for volume of a pyramid is;
V_p = ½Ah
Where A is area of base and h is height
Also, formula for volume of cone is given as;
V_c = ⅓πr²h
Now, we are told that V_p = V_c and that h is the same for both shapes.
Thus ;
½Ah = ⅓πr²h
h will cancel out to give;
½A = ⅓πr²
Cross multiply to give;
3A/2π = r²
Base area of pyramid is given as 154 cm². Thus;
(3 × 154)/2π = r²
r = √((3 × 154)/2π
r = 8.575 cm
F(-5)=(1 - 4(-5) +1 )
=1+20+1
F(-5)=22
Answer:
C
Step-by-step explanation:
The parallel postulate is one of Euclid main axioms. Since it was accepted as self evident.
A is wrong, any two points can be drawn a straight line through. And straight lines exist in plane geometry.
B and D is wrong, the angle measures of a triangle must add up to 180 degrees in plane geometry.
To find how much cinnamon per pound you first divide the $2.40 by the 3 oz to find how much per ounce...so $2.40/3 = 80 cents. Then u multiply that by the 16 oz to get the amount for 1 pound...so .80x16= $12.80 per pound.
Hope it helps!
Answer:
u = 10
Step-by-step explanation:
10 + 6u = 7u
10 = u
Just subtract 6u on both sides.
