Answer:
659.4 cm^2
Step-by-step explanation:
The area of the curved surface of the cone = πrL
= π*7*16
= 3.14 * 112
= 351.68 cm^2,
Surface area of the hemisphere = 2 π r^2
= 2*3.14*7^2
= 307.72 cm^2.
Total area = 351.68 + 307.72
= 659.4 cm^2.

Answer:
-4
Step-by-step explanation:
The point (x, y) = (0, 0) is on the line, so it represents a <em>proportional relation</em>. Any ratio of y to x will be the slope. The choice that makes this computation easiest is ...
x = 1, y = -4
y/x = -4/1 = -4
The slope of the line is -4.
Answer:
On Friday he did not make any bracelets He makes 8 more bracelets each day from Tuesday through Thursday
Step-by-step explanation:
He made 12 bracelets on Monday
For 3 days (from Tuesday to Thursday) he added 8 more each day)
8*3=24
24+12 = 36
M =12
T= 20 (12+8)
W=28(20+8)
Th=36(28+8)
F=36 (still has 36 because on Friday he did not make 8 more bracelets)
8*3=24
24+12 = 36
Answer:
Step-by-step explanation:
In Quadrants I and III, a larger rate has a steeper slope; for example, the line that climbs faster has the steeper slope.
