Answer:Since the volume of a cylinder formula involves the radius, you can solve for the radius and double it to find the diameter.
Write the formula. Volume=π⋅radius2⋅height.
Substitute the dimensions of the shape into the formula. Use 3.14 as the value for π. 791.28=3.14⋅r2⋅28.
Solve the equation for the variable.

0.2 ( 10 - 5c ) = 5c - 16
Answer: c = 3
Step-by-step explanation: Distribute 0.2 to (10-5c)
2-1c=5c-16
Then subtract 2 on both sides and subtract the 5c.
-1c=5c-18
-6c=-18
Then divide -6 to -18
-18/-6 = 3

What is the surface area of the figure? Use 3.14 for π.
847.8 cm 2
2,402.1 cm 2
3,108.6 cm 2
12,717 cm 2
Answer:
Option 3
Step-by-step explanation:
We want to work out the surface-area
This is a cylinder and the formula for the surface area of a cylinder is :
2πrh+2πr^2
^ means to the power of
The radius is 15
The length is 18
2(3.14)(15)(18) + 2(3.14){15}^2
Part 1:
(6.28)(15)(18)
(6.28)(270)
1695.6
Part 2:
First, we do the exponents,
15^2 = 225
(6.28)(225)
1413
Part 3:
1695.6 + 1413 = 3108.6
Answer: 3108.6

Answer:
Angle 3 is 72
Angle 4 is 18
Angle 5 is 90
Angle 6 is 72
Step-by-step explanation:
Sum of straight angle is 180
So 180 = (90+18+x) for angle 3
What is the middle of 1/2 and 3/4
Answer: Try 5/8
Step-by-step explanation: Because 1/2 and 3/4 can also be written as 4/8 and 6/8. And that's how I got 5/8.
Hi! I believe that I have the answer.
My answer: 5/8.
1/2 can also be put as 4/8. 3/4 can also be put as 6/8. Right in the middle of 4/8 and 6/8 is 5/8.
I hope that helps!
A parallelogram and a triangle have been connected along one side as shown below. What is the area of this composite figure?
A 91 m²
B 231 m²
C 140 m²
D 252 m²
Use the figure. Which is greater, angle mTUR or angle mRUQ? Complete the explanation.
some1 PLEASE ANSWER asap :)
Answer:
Angle RUQ is greater than angle TUR
Step-by-step explanation:
Angle TUR is a total of 125 degrees and angle RUQ is a total of 145 degrees. You find the measure of RUQ by subtracting 35 degrees from 180 degrees, this will give you the 145 degrees. So angle RUQ is greater than angle TUR by 20.

the distannce fromm bbaseee to base, incluudding homess platee, on a baaaaseballlll fiellllld is 90 ft. the bases form a square.
If ulu hit a home run, how farrrrr do you have to runnnn to touchhhhhhb all the bases and returnnnnnn to home plateeeeeee
Answer:
360 ft.
Step-by-step explanation:
Each base distance is 90 so since there are 4 bases you solve:
90*4 = 360

Find the TWO integers whos product is -12 and whose sum is 1
Answer:
[tex] \rm Numbers = 4 \ and \ -3.[/tex]
Step-by-step explanation:
Given :-
The sum of two numbers is 1 .The product of the nos . is 12 .And we need to find out the numbers. So let us take ,
First number be x Second number be 1-x .According to first condition :-
[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]
Hence the numbers are 4 and -3
Step-by-step explanation:
[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]

What is the value of x?
A. 7
B. 10
C.18
D. 22
Answer:
B
Step-by-step explanation:
Since all the expressions are on a straight angle (equalling 180) combine the expressions to form on big expression that is equal to 180 and solve.
6x - 10 + 4x + 6 + 7x + 14 = 180
17x + 10 = 180
- 10 -10
17x = 170
÷17 ÷17
x = 10
