The area of a circle is 36π square centimeters. What is the diameter of the circle?A= πr2
A 6
B 9
C 12
D 18

Answers

formula of circle's area is S=πr²
so 36π=πr²
r²=36
r=6
diametr d=2r, r- radius
so d=2*6=12
Answer: C 12

A= r^2 x pithe coefficient of pi is the radius squaredso, take the square root of 36 which is 6 to get the radius and times it by 2 to get the diameteranswer is C 12hope this helps

Adding which terms to 3x2y would result in a monomial? Check all that apply.3xy

Adding and subtracting amonomial requires having the same variables. No matter how big or small theircoefficient is, if their variables do not match, they cannot be added or subtracted.The crucial part in adding or subtracting monomials is their sign. If the signsare the same, retain the sign. If the signs are different, subtract and keepthe sign of the larger number.

3x2y + 3xy (cannot be added)
3x2y + (–12x2y) = -9x2y
3x2y + 2x2y2 (cannot be added)
3x2y + 7xy2 (cannot be added)
3x2y + (–10x2) (cannot be added)
3x2y + 4x2y = 7x2y

Jack wants to fill a rectangular box with sand. The length of the sand box is 3 feet, width is 6 inches, and height is 2.4 inches. Each bag of sand contains 0.15 cubic foot of sand. How many bags of sand will Jack need to fill the box completely?

Answers

To answer the problem above, determine first the volume of the rectangular box by multiplying the dimensions. The length is 3 feet, width is 6 inches which is equal to 0.5 feet, and the height is 2.4 inches which is equal to 0.2 ft. The volume is 0.3 ft^3. To determine the number of bags of sand needed, divide the volume or rectangular box by the volume of sand, 0.15 ft^3. Thus, Jack needs 2 bags of sand.

Answer:

he would need 2 bags of sand
