Step-by-step explanation:
(8.4 * x * 10¹⁰) / (3 * x * 10⁷)
= (8.4/3) * (x/x) * (10¹⁰/10⁷)
= 2.8 * 1 * 10³
= 2.8 * 10³.
Answer:
2A/h = b
Step-by-step explanation:
A= (1/2)(b)(h)
Multiply each side by 2
2A = 2*1/2 *b*h
2A = bh
Divide each side by h
2A/h = bh/h
2A/h = b

Answer:
Curved surface area of sphere = 2πr × 2r=4πr^2;
The new diameter is 120/100 from the old diameter;
2R = (120/100)x(2r);
So, R = 1.2 x r;
Curved surface area of new sphere = 4πR^2 = 4π(1.2xr)^2= 4πr^2x1.44= curved surface of old sphere x (144%);
Finnaly, the increase is 44%.
