Area of the circle is 78.5 sq. units.
<u>Step-by-step explanation:</u>
Circumference of the circle = 31.4 units
2 π r = 31.4 units
2 × 3.14 ×r = 31. 4 units
r = 31.4 / (2×3.14)
= 5 units.
Area of the circle = π r² = 3.14 × 5 × 5 = 78.5 sq. units.

Answer:
El área de un rectángulo de largo L y ancho A es: L*A.
El área de un triangulo de alto H y base B es: H*B/2.
Ahora veamos las tres figuras:
Rectángulo amarillo:
Largo = 40m
Ancho = 45m
Área = 40m*45m = 1800 m^2
Rectángulo blanco:
Largo = 40m
Ancho = 35m
Área = 40m*35m = 1400m^2
Triangulo azul:
Base = 35m
Alto = 50m
Área = 35m*50m/2 = 875m^2
Area total = 1800 m^2 + 1400m^2 + 875m^2 = 4075m^2
Answer:
y-5=1/4(x-3)
Step-by-step explanation:
first you need to find the slope.
5-7 over 3-6 = -1/-4 or 1/4
next put into point-slope form.
y-y1=m(x-x1)
or y-5=1/4(x-3)
The number of years past when Alan was twice Vanessa's age is 14 years.
Current ages :
- Alan = 30 years
- Vanessa = 22 years
<u>We can set up an equation where, x = number of years when Alan was 2 times Vanessa's age thus</u> :
30 - x = 2(22 - x)
30 - x = 44 - 2x
Collect like terms
-x + 2x = 44 - 30
x = 14
Therefore, 14 years ago, Alan's age was twice Vanessa's age.

Answer:
The y-intercept is 2.
Step-by-step explanation:
Assuming that the graph is labelled in increments of 1, the line is crossing the y-axis at 2. That means it's the y-intercept.
I hope this makes sense! ☺
