1 × 12 = 12 2 × 6 = 12 3 × 4 = 12
If h = 13 units and r = 6 units, then what is the volume of the cone shown above?
Answers
the equation for a cone is V=(1/3)hpir^2
if pi=aprox 3.14 for this quesiton and r=6 and h=13
V=(1/3)(13)(3.14)(6^2) V=(1/3)(13)(3.14)(36) V=(13)(3.14)(12) V=(3.14)(156) V=489.84 cubic units
Byron placed bricks in a row to make a border that was 16.9 feet long. Each brick is 1.3 feet long. How many bricks are in the border? A. 13 B. 12 C. 1.3 D. 1.2
Answers
the answer is A. 13, because 16.9/1.3= 13
If each brick is exactly 1.3 feet, diving 16.9 by 1.3 will produce the exact amount of bricks used.
16.9 ÷1.3 = 13
There are 13 bricks in the border (the answer is A.)
