Answer:

∠ ADC = 53°

Step-by-step explanation:

Note the angle between the radius and the tangent is 90°

The sum of the angles in quadrilateral AOCB = 360°, thus

∠ AOC = 360° - (90 + 90 + 74 )° = 360° - 254° = 106°

∠ AOC is twice the angle on the circumference ∠ ADC, thus

∠ ADC = 106° ÷ 2 = 53°

Circumference = 6cm
Let the radius be r.
Therefore, 2πr = 6 cm
Given, height = 8 cm.
Therefore, curved surface area of the cylinder = 2πrh
= (6 × 8) cm^2
= 48 cm^2

Answer:

48 cm^2

Hope you could understand.

A golf ball is hit with an initial velocity of 64 Ft/s. The function h(t) = -16t^2 + 64t models the height h (in feet) of the go

Arlecino [84]

Answer:

Yes, the ball reaches the height of 64 ft

Step-by-step explanation:

Given function

h(t) = -16t^2 + 64t

The maximum value is at vertex and the x-value of the vertex is:

t = -64/2(-16) = 2

Finding the maximum height the ball can reach:

h(2) = -16(2²) + 64(2) = -64 + 128 = 64

The answer is yes
