Answer:

8 inches

Step-by-step explanation:

Assuming the figure is a circle

A = pi r^2

Given the area is 64 pi

64 pi = pi r^2

Divide each side by pi

64 pi /pi = r^2 pi/pi

64 = r^2

Take the square root of each side

sqrt(64) = sqrt(r^2)

8 = r

The radius is 8 inches

Answer:

Step-by-step explanation:

if it is a circle.

area of circle=π r²,where r is radius of circle.

πr²=64π

r²=64=8²

r=8

Part of the area under this ramp serves for storage. Items can be stored only in the unshaded part of the ramp

Mekhanik [1.2K]

Answer:

48.1 m³ available, 2.5m³ not available

Step-by-step explanation:

Tan(X) = 4.5/(5.8+1.7)

Tan X = 3/5

Hypotenuse² = 3² + 5² = 34

Sin X = 3/sqrt(34)

X = 30.96

1/sinX = 1.7/SinY

Y = 61.003°

Third angle: 180 - X - Y = 88.037

Volume

= ½ × 1.7 × 1 × sin(88.038) × 3

= .

= 2.548

= 2.5m³

Available for storage:

½×4.5×7.5×3 - 2.548

= 48.077 = 48.1 m³

Given that answer please

Answer:

<BCA = 44.4°

Step-by-step explanation:

Reference angle = <BCA = C

Opposite side length = x = 7 cm

Hypotenuse = y = 10 cm

Applying trigonometric ratio, we would have:

$sin(C) = \frac{7}{10}$

$C = sin^{-1}(\frac{7}{10})$

$C = 44.427004$

<BCA = 44.4° (to 3 SF)
