The area of semi-circle is 8π cm² with diameter of 8cm.

What is area of semi-circle?

  • The area that the semicircle occupies is that which is contained inside its perimeter. Half of a circle is a semicircle.
  • The area of a semicircle will therefore be equal to half that of a circle. Both the radius and the diameter can be used to get the semicircle's area.
  • The formula used to determine a semicircle's area in terms of radius "r" is written as follows:

Area of circle = πr²/2

  • Area of semi-circle=  πd²/8  is the formula used to determine a semicircle's area in terms of its diameter.
  • The value of the constant is 22/7, or 3.14.

Given:

Diameter = 8cm

Area of semicircle = πd² / 8

=π8² / 8

= 8π cm²

Hence, the area of semi-circle is 8π cm².

Complete the statements about the series
AleksAgata [21]

Answer:

Ok, first in our series we can see two numbers in the Sigma, one bellow 0, and other above, 4.

This means that the value of k will go from 0 to 4, then all the numbers in the sum are:

(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4

So we have 5 terms in our series.

b) to see the sign in each term, we must solve the powers, remember that:

(-1)^n is -1 if n is odd, and is equal to 1 if n is even, so we have:

(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4

= 1 -1/2 + 1/4 - 1/8 + 1/16.

So the sign in each term of the series alternates.
