Answer:
<h2>∠1 = 50°</h2><h2 />
Step-by-step explanation:
<u>right triangle.</u>
∠1 = 180 - 90 - 40
∠1 = 50°
Answer:
yes
Step-by-step explanation:
y <= -4x + 12
(2,4) 4 <= -4*2 + 12 4<= 4 is true
(i.) CA = πrl
CA = π (5*13)
CA = 65π
(ii.) TA = πrl + πr^2
TA = 65π + π (5^2)
TA = 65π + 25π
TA = 90π
(iii.) To get the height of the cone, you have to use the Pythagorean theorem. Plug in the radius for a and the slant height for c.
a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169 Height = 12
b^2 = 144
b = 12
(iv.) v = (1/3)πr^2h
v = (1/3)π(5^2)*12
v = (1/3)π(25*12)
v = (1/3)π*300
v = 100π
Sorry i dont know this answer
