Answer:

Circumference = 43.96 m

Area = 153.86 sq.m

Step-by-step explanation:

here's the solution :-

circumference = 2 × pi × r

=》C = 2 × 3.14 × 7

=》C = 43.96 cm

circumference = 43.96 m

Area (A) = pi × r × r

=》A = 3.14 × 7 × 7

=》A = 153.86

Area = 153.86 sq.m

Big Brothers, Inc. borrows $267,999 from the bank at 18.16 percent per year, compounded annually, to purchase new machinery. Thi
Katyanochek1 [597]

Based on the amount borrowed and the interest per year, Big Brothers, Inc will pay an annual payment of $59,973.15.

<h3>How much will Big Brothers, Inc. pay annually?</h3>

This can be found by using the present value of an annuity formula because the annual payment will be constant and therefore like an annuity.

Formula is:

Present value of annuity = Annual payment x ( 1 - (1 + rate) ^ -number of periods) / rate

Solving gives:

267,999 = Amount x ( 1 - ( 1 + 18.16%)⁻¹⁰) / 18.16%

267,999 = Amount x 4.46865

Amount = 267,999 / 4.46865

= $59,973.15

13POINTS!!!
prohojiy [21]

Answer:

When we know all 3 sides we use the law of cosines

a = 47  

b = 11  

c = 38

cos (A) = (b^2+c^2-a^2)  / (2bc)

cos (A) = -0.7703349282

Angle A = 140.38

cos (B) = (a^2 + c^2 -b^2) / (2ac)

cos (B) =  0.9888017917

Angle B = 8.5826  degrees

cos (C) = (a^2 + b^2 -c^2) / 2ab

cos (C) = 0.8568665377

cos (C) = 31.033 degrees

Angle W would be the smallest angle so it equals

31.033 degrees or rounded to nearest tenth

31.03

Task 3: Use the diagram to find the measure of the angle indicated. Explain your reasoning.
vampirchik [111]

Answer:

m∠ABC = 130°

Step-by-step explanation:

Since ∠ABE ≅ ∠CBD [vertical angles]

(Vertical angles are the vertically opposite angles between two lines intersecting at a point.)

m∠ABE = m∠CBD = 50°

m∠ABE + m∠ABC = 180°

50 + m∠ABC = 180

m∠ABC = 130°

Therefore, m∠ABC = 130° will be the answer.
