Answer:
perimeter = 15.42 cm
Explanation:
Semi-circle is defined as half a circle.
The formula used to compute the perimeter of the semi circle is:
perimeter = πr + 2r
where:
π is a constant = 3.14
r is the radius = 3 cm
Substitute with the givens in the above formula to get the perimeter as follows:
perimeter = π(3) + 2(3)
perimeter = 3π + 6
perimeter = 3(3.14) + 6
perimeter = 15.42 cm
Hope this helps :)
For this case we can make the following rule of three:
1 box -------------> 15 paperweights
x -------------------> 1269 paperweights
We clear the value of x.
We have then:
x = (1269/15) * (1)
x = 84.6
Rounding to the nearest whole:
x = 85
Answer:
There will be needed about:
x = 85 boxes
Answer:
823543
Step-by-step explanation:
7 times 7 times 7 times 7 times 7 times 7 times 7 times 7 times = 823543
you have to multyply 7*7 8 times
