The equation used to find surface area of a sphere is A=4 pi radius sqaured
So i believe the surface area is <span>314.16. In terms of pi thats 100pi</span>
The answer is -1. You multiply the 1/4 with the 5x and equal it to 3 multiplied by 5 and have gotten 15x, then multiply the 3 with the 2, as apart of the parentheses. Lasty you just leave the -9 on the side and solve the equation.
Answer:
3 sets
Step-by-step explanation:
each set is 17.98 (adding necklace and bracelet)
Total is 53.94
dividing 53.94 (amount spent) by 17.98 (cost of set)
Results in 3 sets
Step-by-step explanation:
To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.
We try out all the options:
39² = 1521, 15² + 36² = 1521.
12² = 144, 8² + 4² = 80.
17² = 289, 13² + 9² = 250.
Since 39² equals 15² + 36², option A is the correct answer.
