Answer:
V = 4/3 x pi x r^3
972 x pi= 4/3 x pi x r^3
729 = r^3
The cubic root of 729 is 9 because 9 x 9 x 9 = 729.
The radius is 9 inches, and the diameter is 18 inches.
The volume of the box is 18 in x 18 in x 18 in or 5832 in.³.
Step-by-step explanation:
1.) circumference: 2(pi)r (use the pi sign) Area: pi(r^2)
2.) circumference: 2(pi)5=31.4
area: pi(5^2)=78.5
I’m not sure ab number 3 sorry :\
3(6)+8=26
I think 26 is the answer
Step-by-step explanation:
48 is the answer it is correct check it
Answer: 5 inches.
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where l is the length and w is the width.
If the length of a rectangle is 3 inches more than twice it’s width, then:
Substitute and the area into the formula and solve for the width:
Use the quadratic formula:
Choose the positive value.
Therefore, the width is: 5 inches.
