Answer:
D = √(6 - 9)^2 + (3 + 2)^2]
Step-by-step explanation:
This is an application of the Pythagoras theorem:
D = √ [(x2 - x1)^2 + (y2 - y1)^2] where the 2 points are (x1, y1) and
(x2, y2).
So in this case we have
D = √[(6 - 9)^2 + (3 - -2)^2]
D = √(6 - 9)^2 + (3 + 2)^2]
Answer:
≈ 77 cm²
Step-by-step explanation:
The area of the shaded portion is calculated as
area of outer sector - area of inner sector
= (πR² - π r²) × ( R is the outer radius, r is the inner radius )
= (π × 14² - π × 7² ) ×
= (196π - 49π ) ÷ 6
= 147π ÷ 6
≈ 77 cm² ( nearest whole number )
This is the equation for this problem.
Answer:
Total: $420 (growth of $120)
Step-by-step explanation:
Multiply $300 by 0.025 (2.5%) which is equal to 7.5. Then multiply that by 16 months which gives you $120 added to your $300.
