Step-by-step explanation:
this is totally simple.
the formula for the area of a circle (as you can find with any search on the internet in seconds) :
A = pi×r²
r is the radius.
and once you understand even the most basics of a circle, you know that the radius is half of the diameter.
so, in our case, r = 6/2 = 3 m
the area of the circle is therefore
pi×r² = pi×3² = pi×9 m²
Round all of the numbers to the nearest 10 then solve the problem like normal
18cm (A). Remember to get the radius when you have the circumference is to ALWAYS divide it by 2. 36/2 = 18
Answer:
The answer is 1 and 4
Step-by-step explanation:
.25 x 4y = Y
36 divided by 4 = 9
Answer:
do the opposite of the equation so adding is subtracting and multiplying is dividing
-30-7=-37
-37+13=-24
-24 is the answer
-24+7=-17-13=-30
