7x^8+3x-3
+4x^8+2x+5
=11x^8+5x+2
Answer:
21 feet
Explanation:
Using pythagorean theorem to find the length of the added length of the bottom.
A^2+B^2=C^2 or 4^2+B^2=5^2 or 16+B^2=25
25-16=9 so B^2 is 9 and the square root of that is 3 so B is 3. Then you add 15+3+3 to get 21.
Answer:
22/7
Step-by-step explanation:
22/7 is not very close to pi, but it is sometimes used as an estimation for pi
Answer:
solution:-
diameter of a cylinder (d) = 12 cm
length(h) = 30 cm
curved surface area of cylinder (csa) = ?
we know that ,
therefore , csa of cylinder = 2πrh
r = d/2
or, r = 12/2= 6 cm
Then, csa if cylinder = 2 ×22/7×30
= 2×22×30/7
= 1320/7
= 188.57 Square cm Ans,......
Are you sure the equation does say 2X+16=(-1)?
