the formula for circumference of a circle is 2 x pi x r(radius).
Since this is an improper fraction, you simplify it into a mixed number.
4 goes into 6 1 time. 2 left left over, resulting in 1 2/4. Simplify that into
1 1/2
Answer:
The surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.
Step-by-step explanation:
Slant height of square pyramid = l = 13 mm
Base length of square pyramid = b = 11 mm
Formula of surface area of square pyramid =
Substitute the values in the formula :
Surface area of square pyramid =
Surface area of square pyramid =407 sq.mm.
Hence the surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.
Answer:
it is 385
Step-by-step explanation:
I multiplied 11 by 5 and got 55. then multiplied 55 by 7 and got 385 ;)
Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)
