The wall is a rectangle, so by the pythagorean theorem, the diagonal squared minus the height squared equals the width squared. This gives a width of 42.80 feet. The area of the wall is width (42.80 ft) x height (8.3 ft), equal to 355.26 square ft. The can covers 21.5 square feet, so John needs 16.52 cans to cover the wall. As he can't buy half a can, John should purchase 17 cans of spraypaint.<span>The wall is a rectangle, so by the pythagorean theorem, the diagonal squared minus the height squared equals the width squared.

A^2 + B^2 = C^2.
so 49 + 576 = C^2
625 = C^2
Now find the square root of 625.
25 = C (in your case r)
Answer:
16666666666/100000000000.
Step-by-step explanation:
Answer:
break it in three rectangles!
let the rectangles be A B and C
For A = 4×2
For B 3× (4-2)
For C = 4×3
Total area 26cm²
1000 + 450(36)
1000 + 16,200 = 17,200.
He payed $17,200 for the car.
Hope this helps!
