If the area of the paper is 625 sq in, the length of one side of this square is sqrt(625 sq in), or 25 inches. That's the min. side length of an easel that is to support the whole sheet of paper along its lowest side.
Surface area of cone is a sum of surface of its base and surface of its mantle.
Surface of its base is a circle which surface we will calculate like this:
Sb = pi*r^2 where r is d/2
Sb = 201m^2
Surface of mantle we calculate by:
Sm = pi*l*r where l is length of side of cone.
l =
= 25.3
Sm = 635.8m^2
Total suface is:
Sb + Sm = 836.8m^2
Answer:
150
Step-by-step explanation:
If you had 3 dollars plus the 10 your mom gave you would have 13. Then, if you dad gave you 30 that would be 43. Plus the 100 your aunt and uncle gave you would be 143. Plus 7 would be your answer of 150
Answer:
7
Step-by-step explanation:
A number is divisible by 3 if the sum of the digits of the number is divisible by 3.This statement is a conditional statement. However, it is not in its standard form. A conditional statement is known as an If-then statement.
It should be written as:
If the sum of the digits of the number is divisible by 3 then a number is divisible by 3.
There are two parts of a conditional statement. The first part is the hypothesis, the second part is the conclusion. The hypothesis starts with "if". The conclusion starts with "then".
The conclusion of the conditional statement is THEN A NUMBER IS DIVISIBLE BY 3.
