docker41 [41]

Answer:

8 π .

Step-by-step explanation:

radius increases at a constant rate of 1 in/sec.

dr / dt = 1

where r is radius .

radius after 4 sec

r = 1 x 4 = 4 in

area A = π r²

differentiating both sides

dA / dt = 2 π r dr / dt

Putting dr / dt = 1 , r = 4 in

dA / dt = 2 π x 4 x 1

= 8 π sq in per sec.

Area increases at the rate of 8 π per sec.

If triangle MAS ≅ triangle TAR. Which of the statements could be false? A) segment MA ≅ segment TA Eliminate B) segment MA ≅ seg

BabaBlast [244]

If triangle MAS ≅ triangle TAR, the statement that could be false is letter <span>B) segment MA ≅ segment SA.

This can be false because these two congruent triangles can be 2 scalene triangles. So, segment M</span>A can never be equal to segment SA. This can be true though, if and only if these triangles are isosceles triangles where 2 sides are equal. (See attached file to fully understand).
