Lets get started :)
The First question:
Diameter = 20 ft
Radius =

of 20 (diameter) = 20 ft
Area formula of a circle is
A =

r²
=

(10)²
=100

ft²
≈ 314 ft²The answer will be the second optionThe Second question:
radius of circle = 12mm divided into 20 sectors area
A =

r²
=

(12)²
= 144

ft²
Divide into 20 equal sector areas =
≈ 22.6 mm²Your answer will be the third optionThe Third Question:
90°, sector area = 36

, Radius = ?



and

cancels out
We can now cross multiply
360 × 36 = 90r²
12960 = 90r²
Divide by 90 on either side

144 = r²
Take squareroot
x = 12 inYour answer will be the third option
Answer:
area = 385 cm²
Step-by-step explanation:
area = 5cm * 77cm
area = 385 cm²
Answer:
C
Step-by-step explanation:
If we know that x is greater than or equal to 4, then we should substitute 4 in place of x in each possible solution.
A 4 + 3 ≥ 1 True, it's greater, but it can't be equal to.
B 3(4) ≥ 1 It's greater once again, can't be equal to.
C 4 - 3 ≥ 1 If x can also be greater than 4, then it works both ways. Equal and greater than.
Marty's grandmother cans spaghetti sauce. Last year she canned some specifically for Marty. She ended up with 25 quarts full. Marty noticed, however, that a quart of sauce is too much for her meals (she only cooks for herself). If she wants her grandmother to can the sauce in pints this year, how many pint jars should she buy to put it in?
The fraction 3/5 is greater then 1/2
