Answer:

Radius =3cm

Diameter = 3+3=6cm

Circumference = 18.84

Area =113.04cm²

Step-by-step explanation:

Circumference = 3.14 (pi) × diameter

3.14 × 6 = 18.84 cm

Area = 3.14 × radius²

3.14 × 6²=113.04cm²

A 65 ft. long swimming pool is to be constructed. The pool will be 4 ft. deep at one end and 11 ft. deep at the other. To the ne
pishuonlain [190]

Answer:

Measure of the acute angle = 84°

Step-by-step explanation:

In the figure attached,

ABDE is a swimming pool having length 'AB' = 65 feet

Depth of one end of the pool is BE = 4 feet

And depth of the other end AD = 11 feet

Acute angle between the bottom of the pool (DE) and wall of the deep end (AD) is ∠ADE.

Now from ΔCDE,

tanx = \frac{EC}{DC}

tanx = \frac{7}{65}

x = \text{tan}^{-1}(\frac{7}{65})

x = 6.15°

Now measure of acute angle the bottom of the pool makes with wall at he deep end,

m∠ADE = (90 - 6.15)°

             = 83.85°

             ≈ 84°
