Answer:
1 pi: 3pi
Step-by-step explanation:
Step 1: Formula of surface area and volume of sphere
Surface area of sphere = 4 x pi x r^2
Volume of sphere = <u>4</u> x pi x r^3
3
Step 2: Apply values in the formula
r = radius
radius = diameter/2
r=18/2 = 9
S.A = 4 x pi x 9^2
S.A = 324pi
Volume = <u>4</u> x pi x 9^3
3
Volume = 972pi
Step 3 : Show in ratio
Surface area : Volume
324pi : 972pi
= 1 pi: 3pi
Answer:
Step-by-step explanation:
The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with six sides, so we will let n = 6. The sum of the interior angles in this polygon would be 180(6 – 2) = 180(4) = 720. The angle on the bottom left is a right angle because of the square indicator. We know that this is 90 degrees. If we take the sum of the angles that we know we get 593. 720 - 593 = 127. x = 127.
Answer:
34
Step-by-step explanation:
16+10+6=34
I think that the first person who came along to buy apples would have to buy 12 dozen apples at $1 per dozen. Paul’s sells one dozen, Nick sells 4 dozen, and Ben sells seven dozen. After that, Paul has 3 apples, Nick has 2, and Ben has 1. If they all sent their remaining apples at a price of $3, Paul would earn 9 more dollars, Nick would earn 6, and Ben would earn three. That puts them each with a profit of $10.
I think the answer is 30 because difference means subtract
