Answer:
3.14
Step-by-step explanation:
To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula, and solve as before.
1.4 . Simply divide the two numbers and round to the first number spot to the right of the decimal point.
Fractions can be expressed in three ways: proper, improper and mixed fractions. Improper fractions have numerators that are greater than their denominators, like 54/32. Mixed fraction are fraction with a whole number multiplied beside them. To, convert 54/32 into mixed fraction, let's do division:
___1_____
32║ 54
-32
----
22
The quotient is 1 with a remainder of 22. In the mixed fraction, the whole number is the quotient above, the remainder is the numerator, and the divisor is the denominator. Hence, the converted mixed fraction is
1 22/32.
Answer:
3
Step-by-step explanation:
This is the concept of application of geometry; the distance that the ladder should be placed will be given by Pythagorean theorem.
thus;
c^2=a^2+b^2
where, c=hypotenuse, a and b are the legs
hence;
15^2+12^2+b^2
b^2=15^2-12^2
b^2=225-144
b^2=81
getting the square root of both sides;
b=sqrt81
b=9
therefore the ladder should be placed 9 feet from the wall for it to reach 12 feet up the building
