The area, A, of a circle is given by A = π r2, where r is the radius of the circle. Round all values to the nearest whole number
Artemon [7]

Answer:

A =363 cm^2

Step-by-step explanation:

A = π r^2

r = 11.3

Rounding to the nearest whole number

r =11

pi = 3.14

Rounding to the nearest whole number

pi = 3

A = 3 * 11^2

A = 3 *121

A =363 cm^2

Question 4 (5 points)
klemol [59]

Answer: B (-2)

Step-by-step explanation:

[log base b of a = c] turns into [b^c = a]

You have log base 5 of 1/25 = ?, so it turns into 5^? = 1/25

This part is sort of guess and check, but we can look at it to find the answer pretty easily. First, it's 1/n, so we should use a negative power: 5^-1 = 1/5

In addition to being in the denominator, it's 25, which is 5^2.

So, if we want to put it in a reciprocal as well as square it, we can use -2:

5^(-2) = 1/(5^2) = 1/25

Since -2 (B) is the exponent we place on 5 to get 1/25, it is also the answer to log base 5 of 1/25.

Can someone help me and give an explanation
Kitty [74]

Two triangles: left triangle with y degrees and 40 degrees and right triangle with x degrees.

  • 40 degrees from the left triangle, when adding with the unknown angle of the right triangle, is equal to 180 degrees.
  • Adding left triangle's (third) undetermined angle and x degrees angle (the other same angle), is equal to 90 degrees.
  • The right triangle is an isosceles triangle, meaning two equal angles, and one of them is x degrees. Thus, the other same angle is also x degrees.

----------------------------------------------------------------------------------------------------------

1) Subtract 180 - 40 = 140 degrees. 140 degrees is the unknown angle of right triangle.

2) 140 + x + x = 180 (equation)

  • 140 + 2x = 180
  • 2x = 180 - 140
  • 2x = 40
  • x degrees = 20 degrees

ANSWER: x = 20 DEGREES

----------------------------------------------------------------------------------------------------------

1) With knowledge of x degrees being 20 degrees, the other same angle is 20 degrees, too.

2) Subtract 90 - 20 = 70 degrees. 70 degrees is the (third) undetermined angle

of left triangle.

2) 70 + 40 + y = 180

  • 110 + y = 180
  • y = 180 - 110
  • y = 70 degrees

ANSWER: y = 70 DEGREES

----------------------------------------------------------------------------------------------------------

Whew. Hope this helps you out, and let me know asap if you're confused on any part.
