Mathematics
1 answer:
MrRa [10]2 years ago
5 0

Answer:

  • 2772 cm²

Step-by-step explanation:

<u>Work:</u>

  • 2(π x 21 x 21/2) + (π x 42 x 42/4) = Area of figure
  • => π x 21 x 21 + (π x 42 x 42/4) = Area of figure
  • => (22/7 x 21 x 21) + (22/7 x 21 x 21) = Area of figure
  • => 2(22/7 x 21 x 21)
  • => 2(22 x 3 x 21)
  • => 2772 cm²

Hence, the area of the shape is 2772 cm².

kvv77 [185]
If u raise a power to another power, then u multiply the powers. In this case, u can simplify to 6^2p =6^10

Now you have like bases, so you can set the powers equal to each other. So now, 2p=10. Now p=5

Can someone explain rational and irrational numbers to me? Odysseyware sucks at teaching.
umka2103 [35]
I'm doing geometry for credit advancement in Odysseyware. Brainly and Openstudy are saviors. Anyways. So, and irrational number can't be written as a fraction, but can be written as a decimal. An irrational number has endless non repeating number to the right of the decimal point. A rational number is a number that can be written in a ratio. Which in turn means it can be written as a fraction. Both number of the fraction (numerator and denominator) are whole numbers. Any whole number is a rational number.  <span />
